It took some time, but here the results.
I do seem to have no problem at all with plain 2.4.10-pre6 and 2.4.9-ac10.
As adviced i tried the 2.4.9-ac10 with the preempt patch (without extra
lock-patch posted on lkm)
Just booted the system and i noticed various (4x) "invalid operand"'s, and
the 4 seconds from my systlog are below.

I rebooted the the same patched kernel with the mem=850M option (no
highmem used then), and i'm running it for a few hours but doesn't complain with
any special kernel message. And seems runs _just fine_.
