It all started gradually with it sometimes not coming back from sleep.
This was when I tested 2.6.x with x<=8 kernels from Debian.
Going back to old kernels did not help, though they did run nicely 
for a longer period.

Later it got worse:
The timer made pauses, the system time was off afterwards, 
though the hardware clock was still fine.
Disk and mouse would still move, but any command that needed a signal
for time would not work (e.g. sleep 1) on a shell would pause for a minute.
The machine did not make computing mistakes, it just took a break.
This started after I compiled a lot of KDE stuff during a few
hacking days at aKademy, so maybe this has something to do with overheating.

Currently the system sometimes does not start up at all.
Even when doing a reset there is not startup sound or it hard freezes
a few minutes later.

I did try the test CD from Apple, but could not find anything.
No MacOS on that machine anymore.

I zapped the nvram several time now, without further help 
and my diagnosis is that the hardware has some problems.
