I have no knowledge of the internals of the radeon family, but I am under the impression that they require some hacks to work around bugs in the silicon. There is a rather big patch coming, see
http://www.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.11- rc1/2.6.11-rc1-mm2/broken-out/radeonfb-massive-update-of-pm-code.patch This patch also rewrites the questionable section in radeon_pm_setup_for_suspend. I just found it and have not yet built a new kernel, so I cannot comment on its effectiveness. For reference, the power management issues of the T41 have their own bugzilla entry: http://bugme.osdl.org/show_bug.cgi?id=3022 On a side note, since kernel 2.6.10 I have not been able to successfully resume from acpi S3 + radeonfb any more (T41 2379-DJU, radeon mobility M9) - works under 2.6.9 and 2.6.11-rc1 + vgaconsole. I'm still trying to isolate the problem/waiting for some of the pm code to settle.
