Anybody else with weird KMS modes on ATI?

Now it works.
Ok, now KMS seems to work much better!
BTW, I'm now wondering how to set resolution when KMS is enabled. "vga=value" doesn't seem to apply to KMS too, so even after googling I'm left in the dark.
If there is no way to do so it's really a pain: KMS sets my monitor to it's maximum capability 1920x1440@60Hz, which is not good (nor readable, it's a 19" CRT!), instead of the reccomended 1280x1024@100Hz (@85Hz would be fine too).
I know I can change the XServer resolution, but I also want to use VTs.
Does anybody know of a way to do so?

KMS drivers seem to be still undocumented (that is about 2.6.30, so Intel driver should already be there). I'll try to search more up-to-date documentation or try blind guesses!
I'll let you know!

I found this folder in the kernel tree, but nothing seems to explain KMS drivers.

Even more confused now.
Here I found that radeonfb should be disabled:
Here they suggest to pass video=radeonfb:blahblah
I have the same problem (using 2.6.31 kernel, 3d is not working using radeon x1600 with the radeon driver) and I found a solution: appending this to the kernel parameters fixes the problem: radeon.modeset=1 video=radeonfb:1280x1024-24@60 Now I have dri, all desktop effects enabled, a nice transation from console to X, and averything work very well. Removing video=... or setting it at 32bit depth make dri unusable and cause some other problem switching from console to X or viceversa... an...
I'll give it a try...

For those interested, the answer to my question is: not yet.
From today's IRC:
[17:02] <panda84> sorry if I ask again: is there a way to set default KMS resolution? 1920x1440 is a too high default for my monitor
[17:03] <AStorm> hmm, maybe video=radeondrmfb:<mode> line?
[17:03] <agd5f> panda84: not for the console yet

Code:radeon.modeset=1 video=radeonfb:1280x1024-24@60
It should be (I think) either:
Code:radeon.modeset=0 video=radeonfb:1280x1024-24@60
Code:radeon.modeset=1

There's not currently a way to force an console fb mode with kms. The problem is the kernel fb interface doesn't really have the concept of multiple monitors, so if you want to force a mode, which monitor do you force it on, etc.
