Commenting out MdeModulePkg/Bus/Pci/EhciDxe/EhciDxe.inf from
OvmfPkgX64.[dsc,fdf] doesn't change anything, I still get no mouse
movement and "usb-kbd: warning: key event queue full" after a few
keypresses.

If it's in QEMU, it's only tickled by the OVMF + OSX combination.
Fedora works (around it) fine, and everyone's happy when using
SeaBIOS (and Chameleon, in OSX's case).
BTW, when I do something like this:
-usb -device ich9-usb-uhci1,id=uhci1 -device usb-kbd,bus=uhci1.0 \
-device ich9-usb-uhci2,id=uhci2 -device usb-mouse,bus=uhci2.0
I get an additional pair of uhci1 and uhci2 devices in qtree (at PCI
00:03.0 and 00:04.0, respectively). OS X "System Information" shows
these two instead of the default uhci[1,2] (which are still shown
in qtree at pci 00:1d.0 and 00:1d.1); It shows the default uhci3 at
pci 00:1d.2, and the default ehci.
With this configuration, keyboard and mouse work just fine on OSX+OVMF.
Not sure, but hoping this provides some useful information to you.
I'm still poring over the rest of the stuff you said, which is a
slightly slower process :)
Thanks much,
--Gabriel
