Hmm... that reminds me of the problem I had with a MacBook
(port-i386/37305) in which the second core wouldn't start due to
timing problems associated with USB legacy emulation stuff (timing
calibration was botched due to some SMIs being generated by a "USB
legacy" feature). But that was with NetBSD 4.0...

In that case the problem was solved by disabling such feature.
