i got the radeon firmware to load by editing /usr/share/initramfs-tools/init and
moving the lines that run the init-premount scripts from just after to
just before the lines that load the modules. see attached patch.
it's probably not a good generic solution, but as a quick hack to solve
this particular problem it works and doesn't seem to have any negative
side-effects (although it might on machines with unusual hardware with
fussier load-order requirements...i.e. "it works for me, YMMV"). so i'm
posting it here to document a temporary workaround to help anyone else
who just wants it working ASAP until a real fix is released.
after running 'update-initramfs -u -k 2.6.33' and rebooting, it changed
the kernel boot from this:
[ 0.732433] [drm] Loading RV730 Microcode
[ 0.732463] platform radeon_cp.0: firmware: requesting radeon/RV730_pfp.bin
