Not yet looked at the code (and maybe I wouldn't be able to fix it).
However, the piece of code that I pointed out as being probably the cause of 
the problem was meant to be a fix to another problem. Try to do cat /dev/kmem 
with a 2.4.22-5 kernel (if you want) and you'll see your kernel panicking.

The fix maybe is not perfect but something must go in. Also, if that doesn't 
work, maybe the error is somewhere else (and triggered by this change, as 
easily happens).
