Configure X on an Indigo machine

Hey everyone,


I recently rescued an old Iris Indigo machine that was being thrown away and I'm in the process of making it usable again.
In terms of configuration, it has an IP20 CPU and an LG1 "entry" graphics board. I can post detailed specs if needed.
I've installed NetBSD (5.1, entirely from the CD) and, after a few problems getting it to boot from the hard drive, it now runs very well. The problem with it is that I cannot get the X server working. When I do "X -configure", it says (in its /var/log/.. file) that it cannot find any devices to configure. It does load the drivers and attempts to scan some hardware addresses.
Does anyone know of a solution for this ? Better yet, since I haven't found anything regarding this, do you know of anyone that has X working on an Indigo ? I've even considered upgrading its graphics board to something like a GR2, but I have no idea if it will solve the problem. If you have this thing working, can you send me your xorg.conf file ? 


Thanks,
Ovidiu
