Fun, passing this as a memo to lkml/Debian -- p54pci doesn't seem to
work well for *all* Prism54 FullMAC cards. They technically are the
same and the SoftMAC functionality was possible through a smaller
firmware. But it seems some cards have issues still with p54pci so I
would still enable prism54 as a module but not sure what to recommend
about dealing with two modules on the system for the same device.

Yes I'd restore the prism54 firmware until the coast is clear with
p54pci for all. Its not the case so far as per reports.

I'd say keep it for now.

We've decided to keep things as is from Karmic to Lucid in an effort to
not screw things up for people who already have their wireless working.
This means we'll be shipping both prism54 and p54* drivers.
I have uploaded a new linux-firmware-nonfree package that contains all
the prism54 firmware for all the drivers:
http://kernel.ubuntu.com/~cndougla/linux-firmware-nonfree/
Thanks,
Chase
