2.6.29: fairly stable, even if not as good as with an intel card.
2.6.30-rc4: tons of timeouts, may connect 1 in 100 tries, connection
will drop after some (short) time.

O.K. after trial and error reverting this:
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=47afbaf5af9454a7a1a64591e20cbfcc27ca67a8;hp=853da11b94e674445e93660f47a5f0aeeea09623

brings life back to the macbook with 2.6.30-rc4
(not sure about the iphone anomaly though, I'll keep
an eye on that)
