I pull the latest commit on wireless-testing. Now it seems to work well.
I cannot understand what happened. Anyway the signal level is still
wrong because iwconfig shows a positive value instead of a negative one
(the absolute value seems plausible).

On 2.6.34-rc* kernel I still have the same issue I noticed some times
ago:

Apr 28 00:10:18 eagle3 kernel: [ 1359.907914] rt2800pci 0000:06:00.0: firmware: requesting rt2860.bin
