I typoed. I really meant to say "boot -v". You enter that at the loader(8)
prompt so for it to perform a verbose boot. It gives detailed information
about the boot process, including hardware probing and what it eventually
finds attached to the system.

Here's a couple of things that might put us on the right track:

- Does starting the system with the mouse already plugged in cause the
system to lock up as well?
- Does the machine respond to ping requests when it's "frozen"?
- Have you tried another USB mouse?
- Does this laptop support USB 2.0? If so, you might want to remove ohci
or uhci (they are mutually exclusive on the same ports) and add "ehci".

A boot -v with the mouse plugged in at startup time will provide valuable
insight into your problem.
