(I built X.Org CVS HEAD, but it has the same patch.)

Unfortunately, that fails on my Samsung P35. (Well, at least the display
backlight comes back and the machine doesn't crash.)

Messages by the X server after resume:

(WW) RADEON(0): zero MEMSIZE, probably at D3cold. Re-POSTing via int10.
(II) RADEON(0): Primary V_BIOS segment is: 0xc000
(EE) RADEON(0): unknown reason for exception

(EE) RADEON(0): cannot continue
(II) RADEON(0): BIOS HotKeys Disabled
(II) Mouse[1]: ps2EnableDataReporting: succeeded

Especially CS:EIP looks suspicious.

So what step would be next? IIRC on the P35 needed a crashing VESA server
in addition to boot-radeon. Can that step be added somehow to the Radeon
X server?
