I should troll for Gentoo, then. :-) The good news: I did
get ATi to work using Gentoo (fglrx is an ATI-specific
proprietary program, and may not be needed for all
combinations of drivers). At one point I could flip drivers;
the DRM variant worked to some extent but "tainted the kernel"
as usual; the free variant got the colors wrong in UT2003.
The bad news: It didn't work all that well from a framerate
perspective, and that's the reason I replaced my $60 ATI
card with a $100 nVidia one.
Most likely Bailo is running into a device permissions
issue. There is a DRI section in xorg.conf, and one has
to both set up /etc/udev/rules.d/*.rules (I'm not sure
quite where it's placed) and to ensure that the desired
non-root user is in the video group (by editing /etc/group
if necessary, and relogging in).
In my case, my i915 -- which sucks anyway, though OpenGLX
does work, just not as fast as my home card -- couldn't
connect because /dev/dri/card0 had the wrong group.
Gentoo eventually fixed this -- or maybe their upstream
udev provider did.
BTW -- Sabayon won't boot for me in QEMU. It gets to a
certain point then gets confused. Probably a bug in
their ISO generation; hopefully it's been patched by now.
(Either that, or it really does want an emulated /dev/hda
to play with.)
