Hmmm, this is under NetBSD?

I did find an answer to my problem -- namely a quick hack to
arch/sun3/dev/bw2.c - in one of the initialization routines (match, attach?)
there is code to set framebuffer width/height/type.  The thinking apparently 
was that only a 3/60 with the switch set could have a 1600x1280 monochrome.
I added a case for a 3/260 and now Bob's my uncle and I am running X
just fine (incidently, the device probe line on kernel boot does show
the detected resolution).

The 4/260 also supports only a hi-res monitor, so this fix will need to
make its way to the sparc port as well.  The driver could check the eeprom
byte that is used to flag a hi-res monitor.

Absolutely -- I don't even know if there is a 1600x1280 color monitor
anywhere, and the 1152x900 mono are more than adequate.  And there is
a good technical reason why they are sharper -- no shadow mask in the
tube to have funky alignment problems (and only one electron gun).  The
electron beam paints on the inside of the tube -- there is no dot pitch
for a monochrome tube.

The main trouble with the 1600x1280 is finding a font big enough to be
able to read without strain!  :-)

Not that color doesn't have its place of course.
