That is another bad excuse (btw i don't hear that excuse from devs). I can understand 295X2 does not work (completely) but even that should work with one chip :).

That said most gamers will likely want to have anything with GDDR5 memory, that is enough. Next step are cards with more shaders and bus width 256/384/512.
So this HAWAII is nothing but BONAIRE as i understand, but with more shaders and 512 bus width... so i don't see a single reason (other than these techincal problems in driver development) to not supporting it :). Who knows, maybe this has something to do with not so common 512 bus width on Deskop GPUs, not sure if regs/firmwares need to handle that somehow :o.
i spent a year putting up with a pitiful gaming experience on a 5850 and yet even with all my steam games i refused to go back to windows even on a dual boot. windows at home isnt viable anymore, its too insecure, drm littered, expensive and bloaty, not to mention poor to customise, worse in operation, feel and speed... yup bascially everthing apart from GPU drivers. Then i had a lot more success with a Trinity AMD APU and for a number of months played on most games with frame rates between 20-40fps and with vsync working ok from time to time (only on the opensource driver!). In the end I just bought a GTX760 Nvidia card and apart from vsync not working on some titles im now getting around 60 - 200fps in most of the games (300fps cap in TF2) i play @ 1080p with 4x AA and 8x Aniso + high/utra settings. For under $200 it is a no brainer.
I also tried a 750ti maxewell which was an exellent card for the budget price on performance, enery and cooling. I only got shut because i wanted more and was being greedy :D
So, really i am one of the people who has suffered the longest with AMD cards and whats worse i even a friend of mine who is a long time windows user to try out linux recently swaping from windows 8 after he saw my OS setup he knew it was better than windows. Sadly his 290x crashed the desktop so much he ended up back on win8 and will probably now stay there for a very long time.
im not a typical nvidia fan, i dont like their marketing or ring fencing of technologies or their lack of a decent FOSS driver but in the end im now gaming at the same or in some cases faster than windows 8 on a free linux desktop and thats what i will advise people to buy from now on.
The marketing names are confusing, but the hw breaks down like this:

The relationship between a hawaii and bonaire is similar to tahiti and pitcairn. The main difference as noted is the bandwidth and number of shader cores and RBs. Programming-wise, they are the same which is why this bug has been so problematic.
I just tested nouveau again solely because of this comment, same GPU, without blobbed FW this time

Maybe it's time for modifying VBIOS before attempting honest benchmark? At least for the NV50

I deeply applaud AMD for their OS efforts and focus on buying their products because of it. But lets not pretend that things are hunky dory and that there aren't real issues with the drivers that can necessarily damage your system.
I would definitely switch to open drivers but there are certain problems. First, this is a laptop. Second, the GPU I have (GT 9600M) is really very-very hot even while using nvidia driver. So I'm not sure how safe it would be to use nouveau since it has obvious problems with power management.

And nvidia blob manages to get temperatures over 110°C (no dust, fresh paste, compal JHL90) :D. Idle temperature is just 15°C higher on nouveau, power consumption is probably much bigger issue
Also i have noticed that nvidia somehow has memory leaks and uses way more cpu/ram… I just hope to reach 14 days uptime again
(About my portal2 testing: i forgot to test any valve maps … and fps drops noticeably there to almost unplayable level)
7790 was always GCN 1.1, and yes, it was the prototype they used to test yields of the architecture.

Oland GCN 1.0?

Curacao = Bonaire?
