Hi,

I've now copied the X11R5 distribution for NetBSD-pmax over from 
ftp://ftp.unit.no/pub/NetBSD/arch/pmax/X11R5/ver-5.26, and I've tried to 
start the X server directly, issuing an XDMCP request to another host 
(which I know is configured correctly to accept XDMCP connections):

/store/bin/Xmfbpmax :0 -query some-xdm-serving-host
couldn't open pm 

Fatal server error:
no screens found

The 5000/120 is equipped with a monochrome 1-bit TurboChannel graphics 
adapter and a monochrome screen. When booting from the GENERIC-pmax 
kernel, after reporting on the cache, the display is identified as

mfb0 (mono display)

Using cat, I can't really tell which devices are present; the message 
looks the same for all devices:

# cat /dev/mfb0
cat: /dev/mfb0: Operation not supported by device
# cat /dev/pm0
cat: /dev/pm0: Operation not supported by device
# cat /dev/cfb0
cat: /dev/cfb0: Operation not supported by device
# cat /dev/xcfb0
cat: /dev/xcfb0: Operation not supported by device

Any idea?
