radeonfb problems (console blanking & acpi suspend)

[Alexander Rauth]

I have the following problems with my Radeon FireGL Mobility T2 (IBM
Thinkpad R50p):
1) there is no console blanking nor backlight off powersaving with
fbconsole (no X running nor started since boot)
2) after an acpi suspend the backlight goes back on but there is no data
displayed on the screen (no X running nor started since boot)

If more information is needed for diagnosis then please email me.

Known problem for suspend-to-ram, see Ole Rohne's patches.

I forgot to say that instead of the console blank the cursor disappears
... and reappears after a key is pressed or mouse moved (gpm)

Really? I use 2.6.8.1 on an r50p with radeonfb enabled, and don't 
experience this... But I do run X as well (X.Org) with the X.Org radeon 
driver

I do have problems with a total freeze several minutes after the SECOND 
suspend... But I'm stil trying to track that down...

I use the ati-driver and that suffers from the same problem. Which X
version do you use??? I want to give it a try.

I have still problems with the errors in the DSDT. Do you found any
working solution for this (I tried to modify it by the guides I found by
googling. But it didn't work for me)?

I not sure, but I think there's also a bug in the e1000 driver that
makes suspend/resume break ... do you tried to unload/load it with
acpid.

Sorry for my bad English ;-)
