Turning off the TSC bit will break 64bit Linux (it checks
if the cpuid bits have minimum supported features) and you don't know
in advantage if a guest is 32bit or not.
Ok there is a special BIOS call that the kernel issues to tell

Hi!
I'm having an issue with GFXboot in Ubuntu. If I try to boot one of our
recent iso images, e.g.
http://cdimage.ubuntu.com/ubuntu-server/daily/current/hardy-server-amd64.iso
with a simple "kvm -cdrom hardy-server-amd64" using the kernel modules
from 2.6.24-rc6, and kvm-userspace from git, I
I can apply this when the kvm code is ready (and I think that is close).
One change that I will make to for all three to be EXPORT_SYMBOL_GPL.

If the guest writes to cr0 and leaves the TS flag at 0 while vcpu->fpu_active
is also 0, the TS flag in the guests cr0 gets lost. This leads to corrupt FPU
state an causes Windows Vista 64bit to crash very soon after boot. This patch
fixes this bug.
