[gentoo-ppc-user] iMac ATI Rage 128 OpenGL

[Jon]

Been working on getting OpenGL to work with this iMac, which
has a ATI Rage 128 (Pro?), I have two ways to set it up
while both ways display the standard screen fine, they are
alittle different.

Have installed xfree-drm, and compiled all the necessary
stuff in a ben2 (2.4.22) kernel, enabled DRI. (did not
enable the 'old' drm drivers... ??)

Here's one the ways I run the XF86Config, and each has
different side effects:

1> Use the "fbdev" driver

Driver "fbdev"
Option "UseFBDev"
Option "dpms"
Option "AGPMode" "2"

Running it this way, screen is fine, but mplayer always
plays the smaller size of the screen, (ie, not in full
screen, it won't), if I run an OpenGL app, like tuxracer, or
an OpenGL xscreensaver, it just goes back to 'software'
mode, (atleast tux racer does, xscreensavers that are OpenGL
just don't run at all), but it *doesn't* freeze.

2> Use the 'ati' driver

Driver "ati"
Option "UseFBDev"
Option "ForcePCIMode"    <---- see below
#Option "AGPMode"         <---- off

This way, regular screen is fine, I have to use the Option
ForcePCIMode tho, because if I don't the screen is just
plain messed up, you can't see anything.  But mplayer WILL
play a movie using the entire full screen.  And as far
OpenGL, it will TRY to go into OpenGL mode (tuxracer and
xscreensaver) but then freezes the screen, I can not do
anything I can not move the mouse, but the computer is still
working because in tuxracer, the sound is still playing.

So, the question is, Anyone have gotten any OpenGL working
with an ATI Rage128?  Also, I guess one of the questions is
how can I get the "ati" driver to work in "AGPMode"?

"AGPMode" "1" ?

Any help is apprecated...
TIA..
