Good to see you sorted it out.
i changed mine for the broadcon also and had similar success (so it would on MAC OS X.).
you can see in the forums here that the broadcom is a safe bet for a wifi update.
on my old asus laptop i swapped out a wifi card for a dell one (same reason)
after about 18 months my laptop would not start either. i took a guess and put in the original wifi card and all was well again.
i was also surprised that a failure on a mini pci card would stop the laptop completely.
