Recent changes in the specs that were introduced in commit
740ac4fb08866d702be90f167665d03759bd27d0 were incorrect and resulted in machine check
errors on the PPC architecture for G PHY's with a revision number equal to 1. The
two offending changes are reverted.

John,
This fix should be applied to wireless-2.6 and set to 'upstream-fixes'. I hope is makes
it into 2.6.21 before the final release. The debugging of this issue was mostly done
by David with additional help by Pavil Roskin.
