Hardy LBM, netbook-lpia branch

[Note: Please apply post Monday 12th because of a project release
 timing dependency ]

Impact: rt2x00 wifi signal strength range is very compressed and almost 
meaningless as a metric because of fictional TX status when using the
driver rt73usb and also a very large skewing affect caused by a large 
mix of TX and RX metrics with a small RSSI metric.

Fix: Base signal strength based on RSSI rather than TX and RX metrics
and tweak RSSI base offset to a more reasonable base value.

Testcase: Without the patch, signal strength shows very little change
when close or from from an AP. With the patch, the signal strength
ranges are closer to those shown from other wifi drivers.
