Kevin,
I'm still groping around in the dark here, but...
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.
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.
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.
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.
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.
