Mac OS X How to Install the Latest Graphics Driver for Mac OS X This is a simple tutorial guides you how to update your AMD graphics card driver on Mac OS X (running on any Intel-based PC) to the latest version, to further enhance system performance over 30%, let’s take a look.
Due to the excellent work of Gabriel L.Somlo it is possible to run the emulated Mac OS X on Linux under Qemu/KVM. The changes seem to be minimal, and the operating system emulation works well – as long as you have the Intel CPU, that’s it.
If you have only the AMD CPU, the emulation only works without the KVM, i.e. when you run qemu without the -enable-kvm option. With this option the emulation hangs on the grey screen with Apple logo. Enabling the verbose boot (-v option to Chameleon) shows an empty black screen instead.
This happens because Qemu does not properly pass the CPU vendor to the virtualized CPU when using KVM. For example, booting the Linux DVD installation with the following options:
and running cat /proc/cpuinfo | grep vendor prints the following:
As you see, despite your host CPU being AMD, qemu properly emulates the Intel CPU and sets the options correctly.
However if you add -enable-kvm switch, and run:
and run cat /proc/cpuinfo | grep vendor you’ll see a rather ridiculous picture:

So the CPU model does not change. Since Mac OS X is supposed to only run on Intel CPU, we can assume Mac OS gets really confused when it does cpuid, and halts.

Now, there is a reason why Qemu is doing this. The reason is that the syscall emulation uses different instructions on AMD and Intel CPUs. So if the virtualized guest is specific to the CPU, and This is likely a bug in qemu for which the patch is submitted, but until it makes it upstream, you can apply the patch yourself:
This patch forces the CPU vendor copy even when KVM is being used and a non-Qemu CPU is specified. With this patch Mac OS X installs and runs on the AMD CPU under kvm.

Update: the patch is not needed, as Hin-Tak Leung pointed out in comments,you can pass the vendor as string, and KVM would respect that:
