So it seems fairly obvious that the APU BIOS isn't properly POSTing the wireless card under some circumstances. The fact that it doesn't happen upon a cold boot, and doesn't happen with opon a warm boot if the OpenBSD driver didn't attach, suggests that there is a dependence on the state in which our driver leaves the hardware upon reboot.
