It appears to work fine on my amd boxen.  The only problem
is that I've no idea when it will be possible to finally
disable the init script (shipped in Debian and other distros)
to load the module based on /proc/cpuinfo contents.  It will
do nothing on kernels with this (or kvm-intel) change applied,
but we still need to support older kernels without that feature... :)

Josh, and I'm sure you will be the first who'll file a bugreport
against qemu-kvm in Debian requesting the startup script to be
removed!.. ;))

Thanks,
