Public bug reported:
Binary package hint: linux-image-2.6.27-7-generic
This was supposed to be fixed in 2.6.25 but it was not. The offered
solution is to build the rt2400 "legacy driver" by hand, but that isn't
a solution on a distribution "for humans".
in 7.10 it detected 54Mb/s as all there other machines in the house, now
only 1Mb/s and in 8.10 it doesn't accept to be set to anything higher
than 11M
