Second problem, power button doesn't work. When I pressed it, I has this
error:

ACPI Error (evevent-0305): No installed handler for fixed event
[00000002] [20070126]
Same here, minus the message. (Or perhaps I just don't know where to look.)
Problem also exists in 2.6.20-rc6-mm2. With 2.6.20-rc6-git1 the power
button of this machine works fine.
That's significant - in your case at least the 2.6.20-rc6-mm3 ACPI update
isn't the cause.

Is there anything specific I should test, or Big Bisect time?

This patch should fix the issue...

Alex.
Correct id for fixed buttons.
ACPI_BUTTON_HID_POWERF was changed, but this change was not propogated to button.c,
thus breaking detection of fixed power and sleep buttons.
