ok, it wasn't the stock versions, but the recent versions do crash just
as well (I've just tried it):
Host: 2.6.15.1-skas3-v9-pre8 or even 2.6.15.4-skas3-v9-pre8 (amd64)
Guest: 2.6.15.4-bs1-tls or 2.6.15.4-bs2 (x86)
fs: slackware10.2 x86

boot with: ./vmlinux noprocmm mem=256M ubd0=./uml/root_fs con0=fd:0,fd:1
selinux=0 root=/dev/ubda
(obviously, enable network to get the kernel image)

howto crash it: slap-get --install make
wget ftp.kernel.org/pub/linux/kernel/v2.6/linux-2.6.15.tar.bz2
tar -jxf linux-2.6.15.tar.bz2
cd linux-2.6.15
make defconfig
make
(boom)

If you can't, I could give you access to a limited shell with gdb and
the bits needed.
