There were several copies of this email, so I picked one. :)

I had the crash with 2.6.23-rc8-mm2, so I applied this patch.  Hunk #1
failed, the rest applied with fuzz.  I manually applied hunk #1 and
recompiled.

I am now running with 2.6.23-rc8-mm2 + this patch and things seem good.

(Except for some issues with ACPI battery info moving out of proc and
confusing the heck out of HAL and the GNOME power management scripts).
