I then tried installing netbsd-XEN3-DOM0 and the xen out of the xen48 packages. The system comes up, again in a minimal X with XDM but again without my custom xorg.conf file I get just low screen resolutions. With my custom xorg.conf file I get colorful screen confetti.

Yes, NetBSD/Xen can't use DRI-based drivers, because in our DRI implementation
the physical to machine mapping of addresses isn't handled. Fixing this
probably requires an extention of the bus_dma(9) API, and then fixing
the DRI implementation to use bus_dma(9).
I would expect VESA to work the same way in native of Xen, though.
