Yeah sorry, i was gonna include that in the mail, i apparently forgot. 

I have been running debian, both 32 and 64bit inside it, .18, .24
and .26 kernels, and ubuntu 8.10 .27 kernels, ATLEAST 32bit, i do not
remember if i have run 64bit ubuntu 8.10

I can however give some information that _MIGHT_ (i have no clue myself)
be relevant

on one of the debian guests i had xrandr crash the X server while trying
to change resolution, i did this a few times. Using -vga std.

also, on the ubuntu 32bit guest, i ran qemu with debian stable, where X
crashed during start inside the qemu on the ubuntu guest. This happened
only once.

im quite certain my ram and that is fine, no errors when doing memory
testing etc.


but as said, the kernel is tainted, i dont know if that affects the
results or not, i just wanted to inform in case this can help someone.
That being said, the box has NOT been rebooted since, and i can confirm
that kvm works excellently, i have spawned several VMs and used a tad,
since i wrote the mail.
