They do allow one to specify an alternate DSDT to load, but I'm not
using that feature currently.

Once I finish trying all versions of OSX against all combinations
of piix vs. q35 and up vs. smp, I'll give the Chameleon source a
closer look: ultimately, it would be nice if we had something
Chameleon-like that could be built on Linux (get OSX+Xcode out of
the equation). Maybe getting the interesting bits submitted as patches
against SeaBIOS and QEMU, wherever appropriate.

Currently, I have SnowLeopard, Lion, and MountainLion working fine.
MountainLion needs the 10.8.5 installer (10.8.0 installer hangs at
boot).

Mavericks 10.9.0 installer boots and works fine, but the resulting hdd
image, while bootable, hangs during boot. I want to try the latest
Mavericks installer before moving on to isolate the bits of Chameleon
magic that are relevant to us (QEMU+KVM).

That's about where things are right now :)
