Could that be a remedy for
Aug 7 17:44:10 elektron kernel: Couldn't get a free page.....
Aug 7 17:44:10 elektron kernel: isdn: Could not allocate device-struct.

I have 32 MByte, I killed X and nearly everything, and still I couldn't get
a free page. I had to reboot. What a blame, as some OS2 Guri=u was near me
to help me with my isdn setup!

That would be fine! Guessing parameters isn't a good job. I can read the
source, but understanding it is a different story.
