Same here. For shutdown too. If I remember correctly I has the same
problem when using "Use real mode APM BIOS call to power off" with apm
Maybe its related.

Again, same here. It shuts down a lot faster than with APM though. Maybe
it's doing s.th. wrong. Or maybe echo 2 would be the right thing. I'm
not sure. But that doesn't seem to be suported.

man acpid. At least fn+F4 triggers an event. Debian has a few nice
examples scripts.

2.6.0-test9-mm3 here. 

Btw. did anyone try to use the sysfs to suspend (/sys/power/state)? It
doesn't do anything for me but I'm not sure if it is suposed to work at
