Apparently these links have now been disabled and a moderator on that amd forum has mentioned that the drivers are delayed until monday. The moderator also mentioned that if you already obtained these files "manually" like I did you won't need to download them again at that time.
But in the meanwhile, I have already found the problem I mentioned above with using these drivers on a motherboard with a built in ATI HD3300. The lockup problem with Ubuntu 9.04 may or may not have fixed, and the problems with the drives for users with "x2" cards may also be fixed, but it doesn't matter to me: the same or very similar system lockup still exists on my system. I would have to buy a new motherboard without the integrated ATI HD3300 to get these drivers to work. (Because as I said above disabling the HD3300 in BIOS does not fix the problem.)
I may get a new motherboard... it is possible. Then this problem would be solved. The one I have now was bought when my older 790FX motherboard started having problems. (So I bought the only AM2+ board I could get locally on a sunday.) I might go ahead and get a new Phenom 955 AM3 chip and a new AM3 motherboard and new DDR3 memory. But I'm kind of waiting to find out about the 890 chipset release and benefits.
In the meanwhile it would be good to get a fixed driver that will allow me to use the motherboard I have now. (Or figure out how to tell the driver to completely ignore the onboard HD3300 OR how to see the first discrete video card which is at the PCI:3:0:0 port. If there is a xorg.conf or aticonfig way to tell it to do that. Adding the PCI port in the xorg.conf doesnt' work.)
