The mono framebuffer is on board, all VS3100 and the VS2000 have it.
GPX is a accelerated 4 or 8 bit color frame buffer, available as an 
option for the VS3100, MV II and VS2000. 
SPX is a better / faster / high end / 3D accelerated ???? framebuffer
for the VS3100. It can also be found in the VXT2000 and there is 
a "LCSPX" (Low Cost SPX) for the VS4k. AFAIK there is no doc 
available for any kind of SPX.

The wscons support for the mono framebuffer "smg" is in NetBSD
since 1.5 release. From GENERIC:
smg0            at vsbus0 csr 0x200f0000 # Small monochrome display ctlr.
wsdisplay0      at smg0
lkkbd0          at dz0 line 0
wskbd*          at lkkbd? console ?
lkms0           at dz0 line 1
wsmouse*        at lkms?

Look at the port-vax archive. There are / where two people working 
on it independently.

This is what we all wanted to hear. ;-)

Leo??? That nifty SBus thing?
