Talking of defaults for matroxfb, would you consider limiting the fv:
value default to something reasonable that'll work on all monitors? It
took me several recompiles/reboots to get a setting that would not put
my monitor into auto-powerdown. If you defaulted to fv:60 then it
would work on 99.9% of monitors and then people could override that
upwards. I have a Philips 201B 21" monitor and was using

append="video=matrox:vesa:400"

and this was setting too high a vertical refresh rate for the monitors
capabilities. Adding fv:85 lets it work. The card is a Matrox
Millennium G200 8MB SDRAM.
