I cannot get the Xsun server to run on my Sun 3/260 with a cgtwo graphics
board.  here is what I get when I try to run xinit as root.

First a script with only /dev/cgtwo0 defined.
The ################ signs are before command lines:

################
root:/usr/local/bin/X> ./xinit

Fatal server bug!
no screens found
XIO:  fatal IO error 32 (Broken pipe) on X server "(null)"
      after 0 requests (0 known processed) with 0 events remaining.
      The connection was probably broken by a server shutdown or KillClient.

now a script with /dev/fb defined.
Note that /dev/fb seems to generate a lot of fruitless ioctl() calls:

These problems seem to be caused by failure of an FBIOGATTR ioctl() call.
Besides the above problems, I get a similar failure when I try to find out
if my cgtwo0 or fb device is good by making a FBIOGATTR ioctl() call myself
[I used variations of the program 'constype'].  Could there be a
hardware problem?

Some facts:
/dev is mode 777
/dev/cgtwo and /dev/fb are both mode 666
A cgtwo device is found at boot time, so I know it's in there somewhere.
No /dev/bw* devices are defined.
I am not running on top of Sun windows, so macro SUN_WINDOWS is undefined.
The release 3 server worked fine.
I compiled with version 1.36.1 of gcc.
