I haven't gotten that far on the problem yet. Though I inspected the
verbose booting output and saw that the point where it dies is during
init of the bge driver.

Which wifi card do you have? Right now this notebook has no network
access whatsoever for me. I have tried a number of the Win64 drivers
with ndisgen and none of them seem to work. All of the drivers that I
can find seem to spit out some undefined function warnings on boot and
then throw a trap 12 during ndis init.

I've got the BCM94321 a/b/g/n card in my laptop. (product id 0x4328). I
can't get bcmwl564.sys to detect the card, because it doesn't register
for the 4328 chips.
