Option ROM init x86/x86emu update
- use default display in int 15 5f35
- move REALMODE_BASE to 0x600, 0x500 can be BDA
- add regparm for assembler functions
- use memset instead of own implementation
- YABEL: copy back the IVT, BDA and VBIOS. Some Xorg drivers require this.
- YABEL: use hardware timer instead of emulated timer, because the emulated
timer's base is never initialized (leading to division by zero if the
timer is really used)
