Well this actually sucks. It seems the whole timing issue screws up, if
ACPI isn't enabled. I already tried the patched ACPI stuff, because of
the wrong time, but i didn't manage to to run it succesfull. Considering
the early state of ACPI in 2.4.x, it seems we have to wait for 2.6.x
for stable ACPI support.
At the moment i sum up for 2.4.x on the R32:
APM:
working suspend to ram mode
working standby
working buttons
working thinklight
working battery status
ACPI:
working clock
working power off after shutdown
working keyboard
Any additions?
