I don't know about Ubuntu, but I managed to get radeon.ko loaded early in
the boot process on Debian by including it in the initramfs with a hook script.

It could be loaded earlier and easier, except for udev not being available to
handle the firmware loading when /etc/initramfs-tools/modules is processed.

See Debian bug 561476 [1] for my fix, and bugs 543717 [2] and 557439 [3] for
related initramfs/firmware discussion.
