[Qemu-devel] [PATCH/RFC] Set a (distinguishable) subsystem id for Cirrus

The attached adds a PCI subsystem vendor ID of 0x514D (QM ascii->hex)
for the Cirrus emulation so that you can tell that the system is running
under qemu.  This will make it so that, eg, we can detect that in X and
know that resolutions > 800x600 won't blow up a monitor.

Downside is that it's not an officially registered vendor ID as it looks
like that requires joining the PCI-SIG.  Also, if this is interesting,
it's probably also worth doing for other emulated PCI devices as well.
