Sorry that I dont understand your motivation. If your card is
passthrough, the guest would load the appropriate driver for that. So
why do you care about the cirrus-vga driver?

This is because, even after installing the appropriate driver, there is a conflict of device. Even after I disabled the cirrus driver, the actual driver was reported to be "unable to access resources". Does that sound reasonable then?
