I used to download my source from that site, when
Daniel-san. first took it upon himself to create XFree86 4.3 for
the terminally impatient. Now my 4.3 packages come from:
http://necrotic.deadbeast.net/xfree86/
I don't know how unofficial that is. But there are near nightly
builds of the debian diff's to the X sources. So somebody must
be maintaining them. To be sure, I take the trouble of compiling
from the source.

Did you try "lsmod" on both machines? Did you make sure the
binary stuff was totally purged from your system? I ran into
some problem when I replaced my NVidia with the Radeon. The
binary drivers at that time wouldn't surrender without a fight
(something to do with "diversions" IRC).
Also I get my opensource radeon DRI drivers from a Debian
maintainer's unofficial "site":
http://people.debian.org/~daenzer/dri-trunk/
http://people.debian.org/~daenzer/dri-trunk-sid/
The first URL is for xfree86 4.2, the other for xfree86 4.3. I
had to eliminate the kernel options that would compile the
kernel's native radeon drivers (which would would be replaced by
dri-trunk's own kernel modules).
To be sure I'm running Daenzer's unofficial debs on top of the
official sid X 4.2. The debs allow me to play Chromium and
GLTron with decent explosions. Since the Radeon VE doesn't have
TCL (whatever that means) I get worse fps (100 fps) when running
glxgears under DRI than when running it under plain X (200 fps).
I think Chromium is a better test for 3D acceleration because it
allows you to waste your time in a more entertaining manner.
