Ok, this is getting complicated. So far, I'm getting a bit more success reports that regression reports, so I'm keen to keep this new radeonfb for 2.6.11... There are several issues involved As far as the mode setting is concerned, I'm not sure what's going on whith your specific model, could you please enable radeonfb debug output in the kernel config and send me the complete dmesg log ? As far as the panel blanking is concerned (either during suspend or normal console blanking), this is a tricky matter. It seems that a bit of code that works for some panels won't work with others. So far, I managed to isolate the issue to some panels relying on an inverted signal out of the chip. I'm in contact with ATI to try to solve that problem, it might be possible to get proper infos about the type of panel connected via the BIOS ROM image. Unfortunately, I don't think I'll get a definitive answer before 2.6.11 is released. Note that some users have successfully enabled the powerbook/ibook specific power management code I have in there for thinkpads. I intend t o merge some of that stuff after 2.6.11 is done.
