I do wonder how to set the resolution to something nonstandard. As far as
I can tell with Radeon KMS there is no way: the resolution the monitor
prefers is always selected. This is normally fine for those of us with
LCDs, but for the poor sods stuck on CRTs it seems suboptimal.

(but, yes, a nice fb console with huge numbers of rows and columns which
does not bugger up X acceleration is a major plus of KMS. Another major
plus.)

Boot parameter video=800x600 works for me with Radeon KMS. See Documentation/fb/modedb.txt.

OK, no wonder I couldn't find the docs. fb/modedb.txt is, uh, not the most
obvious of places :)

(though 800x600 is the last-ditch fallback resolution in any case, so
perhaps not the best one to test with.)
