My original problem was that under Fedora 10, the 'radeon' driver worked 
on my hardware, but under Fedora 11, I need 'radeonhd' ('radeon' still 
exists under F11).

Yet through preupgrade this doesn't seem to work.  I don't know when or 
if preupgrade does autodetection - maybe it happens under preupgrade on 
the old X drivers, which isn't necessarily accurate under the new X drivers?

But don't we need to know some of these things about the new target to 
build the proper initrd, and modprobe.cond.d for upgrades when the 
driver is changing for given hardware (especially for the root device)?
