Yes, I've been delving into the sources, NetBSD and OpenBSD, along with
your console frame buffer driver.

I've never seen such a weird-assed frame buffer, *two* separate buffers
for each of the bit depths; 8 bit depth and 32 bit depth? Probably
useful for page flipping to speed up drawing operations. 

All the open source drivers only support 8 bit depth operations. But I
noticed the presence of 32 bit depth buffers, has anyone ever figured
out a way to use them yet? 

In the meantime I've put together the bare beginnings of a X11 driver
for the XVR-500. It now detects the card and says so. 

The next things to do is to write some code to write into the frame
buffer's memory area and see how it all works together. This'll be fun.
