Kevin,
I'm still groping around in the dark here, but...
When I leave the mouse enabled, I get no handle_74 messages, even when I wiggle the mouse. I get handle_09 (keyboard) messages, and it fails earlier when I press lots of keys. When that happens I get a buffer full in inhibit instead of enable.
So I'm wondering why handle_74 never gets called. I don't see anything obvious. I tried to get handle_74 messages from qemu, and didn't see them there either. I'm hoping that this is at least part of the problem.
Thanks, Myles

I wish I could help you more. Unfortunately I'm not an expert on the PS/2 port hardware. I can say it seems to work fine on the epia-m, but who knows.

You shouldn't see handle_74 messages unless something actually requests the mouse. If you want to see them, start freedos, run the "edit" command, and then move the mouse.
As a guess, maybe coreboot isn't fully initializing the ps2 port. If you're getting keyboard irqs on a mouse move that sounds wrong.

I've verified that the mouse works both under qemu and on the epia-m. You just need to run an old dos program that uses the bios mouse calls.
