rt2x00: Stable updates

Hi John,

This patch series is intended for the 2.6.25 kernel, they (should) fix the reported regression for the rt61pci driver (Possibly the other rt2x00 drivers as well, but nobody reported any other regressions for the 2.6.25 kernel yet).

I'll send the patches for the wireless-testing tree separately along with some other patches intended only for wireless-testing.

Ivo
