Wireless only works once, must disable/reenable in bios every boot

Strangest problem: I need to disable/reenable the wlan card on every boot for it to be recognized in OS X. I'm using an Apple branded BCM94321MC, which is natively supported and worked fine in my 901. The first time I booted the wireless worked as expected. On second boot, no airport card is detected. Going into the bios and toggling disable/enable fixes it for the next boot. I need to do this every time I turn on the computer, or the wireless card wont be detected!

I'm dual booting XP, and the card works 100% of the time in XP.

I have tried both a DSDT modded bios, as well as PCEFI v9 w/ DSDT override + stock bios. No difference.

If anyone has any ideas, please post! Thanks.

I found the solution! I had to disable Boot Booster in the bios! I figured this out right before finding this thread.

I didnt consider this before because I know for a fact I had boot booster enabled on my 901, and this card worked fine in OS X. BUT… for whatever reason I always got a message on my 901 that boot booster failed, so essentially it was off!

Just came across this same issue on my 901 after a new RunCore SSD Installation. Thanks for the post, I would have never figured this out.
