Sun video configuration notes

Some suns can have their video tweaked with an eeprom variable like:

eeprom output-device=screen:r1280x1024x76

This should be able to jack up a Turbo GX+ to 1280x1024, beyond its
default 1152x900.

If this variable gets an invalid value, you may find yourself with a
black screen.  In this case, you may be able to ssh in and change it
to something else using the "eeprom" command, or you may prefer to use
Stop-N to restore the NVRAM to factory defaults.

Looks like Sunblade 100's use m64config.  EG:

m64config -prconf to get current settings, along with a list of viable
resolutions

m64config -res 800x600x60 format to set resolution, followed by a reboot.

Another relevant program for some Suns is fbconfig
