Ole Rohne told me to use lcall $0xffff, $0 in wakeup.S, which I did in
the first place and nothing happened. Since according to him this is
supposed to reboot the computer I concluded that there is either
something wrong with the wakeup-vector or with _WAK (there is no BFS in
my DSDT). Thus I tried to jmp to the wakeup-vector from
acpi_enter_sleep_state wich worked (besides it led to a general
protection fault after a few instructions - I guess thats because I am
not in real mode?!). So it seems it never even gets there when resuming.

So I did - as you suggested - disassebmle the DSDT and had a look at the
WAK method (attached) - but everything seems fine as far as I can
tell...so I am totally stuck now. 

Next thing I wanted to try is to put system in real mode before jumping
to the wakeup-vector just to have a look if that really is the
problem...

Any suggestions?

Thank you for your help anyway. I really appreciate it.
