This may not work for every kernel and every machine, but it worked for
me.

gerbil: 2.2.17pre20-Ben3
machine: 1999 iMac DV SE
X: 3.3.6
YDL: CS 1.2.1

A line has to be added to Yaboot.conf (in your bootable HFS partition)

        append="video=aty128fb:vmode:17,cmode:24 hdb=cdrom hdb=noautotune"

this goes into whatever section you're going to use to boot linux.

(I'm not sure what each part of this command does. aty128 sounds like
the ATi 128 Rage Pro card in the imac. cmode:24 makes me think of the
24-bit color that's going to be invoked. Declaring the other hdb things
does something, but I don't know what it is. =)

The colors of the boot penguin are way off. Nasty.

Upon arriving into linux (the resolution was different) I launched x
with
the command

        startx -- -bpp 24

i later tried 16 (instead of 24), with no luck.

The console monitor is a wee bit off to the left: not unusable, but
irksome. xvidtune, which I ran from within X Window, was very
uncooperative; it told me that everything I did was impossible. I ran
it as root, too, so I don't know what's up wid dat.

Thanks to Benjamin Herrenschmidt for posting this advice; it was staring
me in
the face this whole while. gah. The Purloined Server.

peace

philippe
