acpi on thinkpad T42p

[doug at safeport.com]

I am trying to get suspend/resuume working. I think what I have is a problem in
the Xorg ATI driver, but I am not sure and would greatly appreciate some
guidence.

I am running 6.1 and Xorg 6.9.0. The S1 and S3 states worked with the only
change being commenting out the DRI module in xorg.conf. My video shows as:

   none2 at pci1:0:0: class=0x030000 card=0x054f1014 chip=0x4e541002 rev=0x80 hdr=0x00
       vendor   = 'ATI Technologies Inc'
       device   = 'Radeon Mobility M10 NT (RV350-WS)'
       class    = display
       subclass = VGA

Upon a resume from an S3 state the background is not restored, looking rather
like a zebra (black and white lines). I can restore the background by forcing
KDE to redraw it. Everything else except the built-in mouse is restored. I am
using the ipw wireless driver, usually the network also comes back

Loads and ssetting are:

   kldstat

    hw.acpi.verbose: 0
    hw.acpi.disable_on_reboot: 0
    hw.acpi.reset_video: 1
       :
    dev.vga.0.%desc: Generic ISA VGA
    dev.vga.0.%driver: vga
    dev.vga.0.%parent: isa0

Am I correct in thinking the problem is in the ATI driver?
