Comment 14 for bug 108382

Brian:

I don't know how relevant it is, but here is some info from the Feisty
Device Manager on my machine:

Sis85C503/5513 (LPC Bridge)
PS/2 Port for PS/2-style Mice
IBM Enhanced (101/102-key, PS/2 mouse support)

If you don't have access to a similar machine, I imagine it would be
difficult to reproduce the PS/2 mouse problem.

If there's any other info I can help you with (leaving aside
near-impossible tasks that only people like Loki-uk can achieve), then
please let me know.

Bob
