[ltp] (T41p) Radeon+more interrupts (powertop) after console or resume - vblank patch problem?!?

[Nils]

Hi there,

I've a strange problem with Xorg. After a fresh system restart and login into 
X everything works fine. 

Powertop shows: (always without WLAN !!)
< 20 Wakeups-from-idle per second.
C4 (97,3%)  
600 MHz   (100,0%)

Then I switch to console-screen and back to X (or sleep/resume with the same 
result) and now the powertop application shows:
~ 80 Wakeups-from-idle per second.
C2 (87,3%) 
C4 (0,0 %)
600 MHz   (100,0%)
and I see this new line:
 72,6% ( 96,8)   <interrupt> :Intel 82801DB-ICH4, radeon@pci:0000:01:00.0

It seems that the vblank-patch or everything else has to be reinitialize the 
radeon card. I use the following really ugly patch:

1.) After system reboot I save the radeon state in the working state at low 
power consumption with: "vbetool vbestate save > /tmp/vbestate"

2.) After changing to the console-screen or resuming I reinitialize the card 
with: "vbetool post && vbetool restore < /tmp/vbestate"

-> The screen looks a little bit corrupt after the second command, but it's 
working.

Does anybody know a better solution or how to modify the vblank patch? Or is 
this another problem?

Thanks,
Nils
