Ah, good one. Yes that fixes things. Looking at other nv4x cards, it seems that
we are not using MSI on the C51 / C61 /  C67 / C68 / C73 either, these all set
the mc-subdev oclass to nv4c_mc_oclass which results in msi not being used.
I've written (and tested) a patch to do the same for nv46. I'll attach that
here and send it to the list.

Regards,

Hans
