I've got to imagine that the ne2k NIC wil do the job, though I'm kinda
suprised there's no rtl8139 support.

Excellant - I assume you've got that setup to use VirtIO for F9/10
and Ubuntu Hardy ?

That's the situation we've got already - we compile Xen and KVM to use
the rtl8139 nic since that's the best lowest-common denominator. It was
a barely passable approach so far, but with VirtIO it is now past its sell
by date and we have to key off os type/variant. If we don't then we'll
be limiting guests to 1/100 of the their potential performance. Not cool
