I've having this problem on a Toshiba A80-132 (Equium) laptop.
Occassional crashes that require hard-reboot. sometimes I need to remove
the battery. Although oddly, often I can ssh in from another machine and
reboot.
These crashes started after a clean install of 9.10. No problems in
9.04.
Wireless details are:
06:02.0 Network controller: Intel Corporation PRO/Wireless 2200BG [Calexico2]

Subsystem: Intel Corporation Device 2741
Flags: bus master, medium devsel, latency 32, IRQ 22

Capabilities: [dc] Power Management version 2
Kernel driver in use: ipw2200
