Yes it's good to pass video parameters to old world maschines, at least
I do this on a G3 Powerbook Wallstreet. I've found them on the web:
video=atyfb:vmode:14,cmode:32,mclk
But in my experience this only effects the command line. In Ubuntu you
should find the options for x under /etc/X11/xorg.conf.
I don't know bout the lomard, but the wallstreet has massive problems
with the video resolution of newer kernels than 2.4.
My 1998 Wallstreet/PDQ works OK with Ubuntu "Hoary," using
their stock kernel version 2.6.10-5-powerpc. It's not absolutely
perfect because the video driver dumps a bunch of lines into dmesg
every time X starts or changes resolution, but VISUALLY it works fine
at 1024x768 and the lower resolutions too.
Here's what I put in the BootX kernel parameter.
video=atyfb:vmode:14,cmode:8,mclk:71
(For some reason using the syntax like 1024x768@16 has never worked on this machine with the
Ubuntu kernels I've tried even though it worked on Debian last summer, so in that
manner there's something different about the atyfb driver.)
I'm attaching my /etc/X11/xorg.conf file but I think I've only modified
it slightly from the default. (I've never had trouble getting X running
on this machine.)
