The main reason for this (if my understanding's correct) is that it makes getting decent video running on Windows much easier - both 98 and 2000 ship with drivers for the Cirrus card, but no generic VESA driver. In theory I guess the emulated card could prove to be a bit faster in future too, by moving some drawing operations from the guest to the host. > Basically the main thing I know about gfx support is that it should be > way faster to support native cards (I've got a GeForce 4 MX 64MB DDR in > my 1 Ghz iMac, for instance) instead of emulating a card.

Do you have a link that describes this native video card support? If it can take your system's primary video card and make it avaiable directly to the emulated system, then I can't see how it'd work. However, being able to use a second video card that's in your host system but not used by the host OS sounds like more of a possiblity. Depending on how development of the PCI proxy patch goes, I guess it might eventually be possible to do this in Qemu. Thanks Leigh
