you do not have to specify vesa,pixclock,hslen and vslen, as you leave them on defaults.
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 usingQuoted 5 lines
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.

Are you sure that it did not run out of horizontal sync, or something like that? vesa:400 == vesa:0x190 == 1152x864/60Hz... And it powers up in 60Hz, at least here ;-)
See timmings array in
drivers/video/matrox/matroxfb_base.c- all videomodes except XXXx400 powerups in fv=60Hz unless you specified fh/fv/pixclock. XXXx400 powerups with fv=70Hz, like standard VGA does.
Looks like one you've already fixed. I've retested and recreated it but it only happens with 2.2.13 not with the other two kernel sources I have (2.2.18 and 2.4.0). I also misinformed you about the way to recreate it, I had specified only append="matrox" in my lilo.conf. It was 2.2.13 that I did my experimentation on to get it to work in the first place and never bothered to retest afterwards. Sorry for the false alarm...
