great! hope you'll become as addicted as I became years ago... =)

what's the exact kernel-log output for the prism54 driver while
initializing?

read up about the hotplug support for pci-like devices...

well, static linkage does not work yet, especially for cards that a
plugged in permanently; (reason is: the firmware can't be uploaded
since there's no fs mounted yet where one could get the firmware
from... and firmware uploading is done at probing-time)

...but I'm working on making the situation better (i.e. retry firmware
uploading at device open() time... but I have to clean up some stuff
before) :-)
