Some system biosen (called out to by laptops) use opcodes (e.g. LIDT - 0x0f01)
 that x86emu does not support. This results in the emulator dying horribly,
halfway through the emulation (which will be logged at the end of your trace)

Should this apply to you, the following patch will ignore interrupts calling
to the system bios, and should avoid this problem
