What about the first upgrade issue, the lack of firmware? If the unknowing
user does something simple and innocuous such as exit their X session for
whatever reason, before installing the apparently critical firmware, the
display manager will exit the working session and dump them into a broken
screen.

But it *was* loaded by udev. I don't run 'modprobe radeon' at any point
between the two tests. After the broken startx, it's loaded, which is why
it is in the dmesg output I sent you.

I went looking for that and found fglrx-driver's file, from the removed but
not purged package. I purged it (from the console), then did the first
startx, and the same thing happened again - I had to run startx twice.
