Kernel driver in use: radeon

Hi wabe. This whole radeon thing is so confusing I thought I'd mention
one more very confusing detail that I had to fix before I got the open-
source ati/radeon driver to work correctly:
First I tried starting my X session with no xorg.conf file at all.
That didn't work but of course I can't remember now what went wrong.
(That was already more than 24 hours ago :)
Then I generated an xorg.conf in the old way using 'Xorg -configure'.
That file didn't work right either.
Then I finally realized that the generated xorg.conf had, in the
Section "Device" section, this line:
Driver "radeon"
But that's not what we want. To use the open-source ati driver I
changed that line to read:
Driver "ati"
And that's when everything finally started to work perfectly.
One more thing that confused me: the xf86-video-ati package doesn't
install any kernel modules. It installs only these two files:
/usr/lib64/xorg/modules/drivers/radeon_drv.so
/usr/lib64/xorg/modules/drivers/ati_drv.so
but to use those files you need that Driver "ati" line in xorg.conf.
<sigh>
