Hello all!
Title says it all.
Without "-enable-kvm" qemu-system-x86_64 boots the ubuntu 8.10 cd image fine
(slowly) and with "-enable-kvm" I get corrupted graphics and can't continue past
grub menu. But it does boot a winxp disk image fine, with and without KVM.
Host is Linux 2.6.27.7 on a core2duo, running in 32 bit mode.
qemu is current svn trunk.
How can I help debug this?

It's a KVM module bug. You need a patch to your KVM module. See
Glauber Costa's patch about not deleting slots properly on kvm-devel.
