If it's a programming problem, might it be fixable in the firmware (rt2561s.bin)? If not and given this is a Belkin card (model F5D7010), I guess there could be thousands of them out there, so some note on the Devices section of linuxwireless.org might help other users. In fact two versions of this this model are currently shown as supported by the b43 driver, but this, which has worked fine until now, isn't mentioned at all.
