Duncan, many thanks for the quite detailed explanation! It is much 
appreciated.

I will do as suggested and switch to a text console before hibernating. I 
still don't understand why this should help, as the TuxOnIce user 
interface is in text mode anyway, but whatever. I tried hibernating (to 
disk) for another two times, and it worked just fine. Did not dare to 
try suspending (to RAM) yet.

This night I tried again. First attempt did not succeed, hald-addon-stor 
failed to freeze. I had this before, and just tried again. The next 
attempt _seemed_ to have worked, and the system powered down. But this 
morning it did not resume, it just bootet like if it was shut down 
regularly. 

Here is the syslog. Only two lines were logged for the last attempt? Or is 
this because the file system was not synced and the rest of the log did 
not get written to disk? If so, would there be some options for ext3 
journaling to make this work?
If not, I should try Henrik's idea of logging to the serial port.
