Yes it is 0x7B. So even if you tell 2008 to ignore signing from the boot
menu it will still blue screen like that? If so, the only alternative is to
run with your test-cert signed drivers in test mode (aside from, obviously,
purchasing the legitimate certificate and signing them properly).

This seems like a nasty situation...
