as far as i can analyze, kernel tries to allocate memory but somehow fails to do it, but as opposed to a ENOMEM or some
message alike, a crash follows.

to describe to situation more clearly, i was wise enough to open a webpage with tons of images in my browser, and the browser
started to grab enormous amounts of memory to draw them in. the kernel swapping element seemed to go berserk and after
listening to the harddrive crying out loud for a mere minute, the system freezed and stopped to respond (yes, even the
sysrequests didn't respond anymore).

this is not the first time this has happened :

hope that helps.
as for now i'll probably try to get 2.6.10 into my box and see if the problem occurs again.
