ACPI Sleep on Thinkpad R40, wakeup fails for X11/radeon

[Martin Cracauer]

Any ideas how I could fix suspend/resume on this Thinkpad?


I have a Thinkpad R40 running 6.0-current.  It has a Radeon 7500 with
32 MB.

When I suspend it with zzz (ACPI actice), the machine sleeps and wakes
up fine except the X11 server is unhappy.

The X11 server has some graphical corruption, never updates graphics
and does not take keyboard input (Control-Alt-F2 etc are also disabled
and just beep).

Network login and top(1) shows the X11 server with 103% CPU :) and an
strace shows an endless stream of:
ioctl(8,0x20006444,0x0)                          ERR#16 'Device busy'
[same call forever]

dmesg, acpi list etc are on:

Here's some logs:
