Every time I encounter big enough trouble about some chipset to have to
learn a bit about its internals, I usually learn about its engineering
flaw. BCM43xx has the following one: the chip internally is 32 bit,
though it sits on 64 bit bus. (Take that with a grain of salt, it's
been long time since I looked into that crap).
Once I discover the flaw, I add particular hardware in my black list
and do my best to not buy anything containing it. Broadcom as a whole
is not in my black list, they have great hardware, but their BCM43XX
is, even if they corrected their design flaws since.
I would replace that if possible (Intel would be great candidate), or
use USB adapters others suggest.
Just my $0.02

Hey ... Thanks for your help everyone.
Looks like I will need to try my hand at the compiling process or
purchase an intel based chip board.
