Do you have a patch for secondary passthru on Xen 4? I seem to recall
somebody had been successful with secondary passthru using an
additional patch but I cannot find it.

I'd like to give it a try, I have one system with 2 x radeon x1950's
and another with Quadro FX380 and GeForce 9500 GT, both currently
running X, xen 3.4.2 with 2.6.31.12 suse patched dom0.
