Using a version of WinPcap that blue-screens, would be my guess. ;-)

WinPcap 4.0 beta?
The supplicant has no code that runs in kernel-mode, so it can't cause a
blue-screen. (At least, not directly.) However, WinPcap does (it has a
kernel-mode protocol driver that it uses to capture the frames), and
this driver (in WinPcap 3.1 and earlier) has at least one bug that
causes a BSOD when a driver is unloaded.
(Well, actually, the BSOD happens on the next NDIS OID request to a card
*after* that card's driver is unloaded. But the supplicant seems to
make NDIS requests fairly often.)
In theory, the code that the latest supplicants have to listen for WMI
adapter-removal events should fix this, but there's still a race between
the WMI event being delivered and the supplicant making an NDIS request,
so it's not a perfect solution. You need WinPcap 4.0alpha1 or later to
really fix the problem.
