Patches 2-5 are from Anthony and I just rebased them on top of master. Patch6: fixes a crasher in vmware when X starts inside the guest. I've booted these with an F12 LiveCD and all seems to work.

KVM requires that all mappings of the VGA vram have dirty tracking enabled on them. Any access to the VGA vram through the VBE mapping currently fails to result in dirty page tracking updates causing a black screen. This is the true root cause of VMware VGA not working correctly under KVM and likely also an issue with some of the std-vga black screen issues too. Cirrus does not enable VBE so it would not be a problem when using Cirrus.

This is because it performs a very simple memcpy() to blit from one surface to another. We currently hardcode a 24-bit depth. The surface allocator for SDL may, and usually will, allocate a surface with a different depth causing screen corruption. This changes the code to allocate the DisplaySurface before initializing the device which allows the depth of the DisplaySurface to be used instead of hardcoding something.
