So I have a nice patchset emulating this instruction (quite a pain,

Turns out the real problem is somewhere else - the guest is not
detecting VBE properly so it is forced to use the old slow vga
access. Not sure what the root cause is.
Is this with -vga std or -vga vmware?
Yes (both reported, I confirmed with -vga std).
Is this a VESA driver in the guest?
So it seems from the Xorg log. Boot a Ubuntu 9.10 cdrom, on
qemu-kvm-0.11 it boots fine and fast, on 0.12 it fails on emulation
(unless you apply my patchset, in which case it works, but is incredibly
slow).
