Also, the command "words" helps here; it seems that sun's support for 
fixed resolutions, e.g.

	setenv output-device screen:r1024x768-something-something

is actually a call to an OF routine attached to the frame buffer; 
"words" will give you the list of OF routines attached to that node 
in the tree, and that, (among other things) includes the supported 
resolutions for frame buffers.

The SUN Frame Buffer FAQ is very, *very* helpful on questions like 
this; it can be found at http://www.sunhelp.org/
