There's one more thing I forgot to mention; deinitialization does not seem to
work correctly. If I remove the mantis driver and reload it, the CAM is no
longer detected correctly (when the 50211 driver tries to read the
identification bits from the CAM memory space, they simply don't match
anymore). This is annoying, as it means a reboot is required whenever one
wants to test a new fix, but I haven't been able to figure out why it
happens. Just wanted to mention so that nobody bangs their head in the wall
too much due to hitting that problem :-)
