we might have to do a step by step upgrade for this. Something like
install everything in /lib/firmware/`uname -r`/ and create symlinks for
a grace period of the next sixt month or something like this.

These are details that have be sorted out, but should not stop us to get
this right.

And before you say anything. You can expect that firmware loading
from /lib/firmware works almost everywhere. At least this has been for
the last 3 years or so. Remember that we do have request_firmware() even
in the latest 2.4 kernels.

Marcel
