[Voyage-linux] Some hints or related docs

2.6.38 is not quite so bleeding edge, though YMMV. The only problems that I
know about are some difficulties with the mac80211 driver implementation for
running atheros cards in master mode (in specific circumstances)...

Reading through the various notes may give you a better idea for the
appropriateness for your specific situation.

Cheers,
