I'm glad to hear that Mac OS 10.5 boots to the desktop. If this  
driver does cause problems it could be a problem with Mac OS 10.5, or  
the driver. Either way, a command-line option for disabling or  
altering this driver might be the solution.

The mouse and keyboard drivers for ADB were removed from the Mac OS  
in Mac OS 10.5 I think. Could you try the USB keyboard and mouse?

Do you think you could post a picture of Mac OS 10.5 running in QEMU?

Thanks.
