Try --preload=radeonfb instead?  Also, unsure if you stated your
kernel boot line, but make sure you don't start another framebuffer -
your syslog messages indicate to me that the area radeonfb's trying
to occupy is already taken.  So no vga= options, and throw in a
"radeonfb" for good measure.  Obviously ensure the force_sleep line
is still there in modprobe.conf too.

As a word of encouragement I have it working fine in FC4 after the
above measures - the only other issue is, as has been mentioned, your
model doesn't work with it.  But I'm skeptically of reports that any
(at least) T* models don't, honestly.

In return, if you can suggest how I can *change* radeonfb resolution,
I'd be grateful!  As discussed before here, I've tried everything
I've read:

video=radeonfb:1024x768
video=radeonfb:mode:1024x768-24@75

and hardcoding resolution in modprobe.conf - none work on Fedora Core
4.  Yet to try on Ubuntu Breezy.  Fedora kernels compile radeonfb as
a kernel module, for interested parties: I haven't tested with it
built in (and don't want to rebuild just to change resolution).
