Right now - no. Not even in -current. This has nothing to do with any
hardware incompatibility - it's XFree86 ands its rather odd and
inflexible method to access PCI framebuffers. We should really rewrite
the NetBSD-specific part at some point.  To make it short: XFree86 wants
to mmap PCI framebuffers via /dev/ttyE* which allows exactly one device.
You can have more than one SBus framebuffer though - they're accessed
via /dev/fb*, one file per framebuffer. So if the graphics card you want
to use is not the console and not SBus or UPA it won't work. To be the
console the card needs Sun-specific firmware.

have fun
Michael
