We did try XFree86 4.4.0 and it worked okay also. What kernel version
do you have? We put 2.6.7 on Stewart's machine.
As an attempt to summarise the steps that worked for Stewart's iBook
G4 (Radeon 92000 M9+ 5c63) see the following:
1) We downloaded the source for the kernel 2.6.7, made and installed
it on Stewart's machine. Doing a `strings /boot/vmlinux-2.6.7 | grep
-i radeon' showed, amongst others, a string something like `5c63
Radeon Mobility M9+. After booting into this kernel `cat /proc/pci'
showed the video card correctly identified, though `lspci' still
showed it as unidentified. See sites such as
http://www.linux-sxs.org/upgrading/migration.html for information on
changing the initialisation scripts to work correctly with 2.6 series
kernels. This site has some good links. We followed the suggestions
in this site and links.
2) I downloaded xorg-x11-6.7.0-5.src.rpm from Fedora 2. To make it we
also needed freetype-2.1.4-5.src.rpm since it needs a later version of
freetype than that which accompanies YDL 3.0/3.0.1 (strictly it
requires 2.1.7 or later, but I did not find that on the local (Monash)
mirror and 2.1.4 seems to be used by the maintainer, so I just
modified the spec file). As xterm no longer seems to come in the
archive I also downloaded xterm-179-5.src.rpm from fedora 2.
These all made quite happily, creating a raft of ppc.rpm files. To
install them required doing a `rpm -qa | grep xfree' to find which
rpm's were installed, then doing a `rpm -Uvh -nodeps ' followed by an
appropriate list of new ppc.rpm's. The -nodeps was because a range of
items have XFree86 hard coded for the Xserver. There are some things
that then need doing if the new Xserver worked.
3) I edited the yaboot.conf to include a stanza:
image=/boot/vmlinux-2.6.7
label=2.6.7
root=/dev/hda12
read-only
initrd=/boot/initrd-2.6.7.img
append="video=radeonfb"
The accelerated X11 worked with either XFree86 4.4 and with Xorg's X11
(6.7.0-5). I had to hand edit both the XF86Config and/or xorg.conf
file to get it to work fully. I append the xorg.conf used to this
email. Using DRI glxgears in the default small window gave around
1400 fps for 16 bit and around 750 fps for 24bit.
Here is the xorg.conf from /etc/X11
