Yes - I hadn't tested this model in particular, and this one is a little
less obsolete compared to the ones I found without NMI support (a 64-bit
Prescott and a 32-bit Yonah), but I still believe it's saner to treat
them as obsolete.

Can you please run vmxcap (from QEMU's git repository) on that processor
and include the output?
