Suspend freezes system on my Thinkpad X41

[Jordan Sissel]

Subject says it all. Attempting FN+F4 (suspend) or acpiconf -s 3 or -s 4 all
cause the system to halt.

Specs:
Thinkpad X41
6.1-RELEASE GENERIC
Atheros 5212
Broadcom BCM5751M
SATA (ICH6 SATA150)

Freezes are non-recoverable. Even hardware functions (such as lcd dimming)
cease. Seems like the system has half suspended, but the LCD is still on and
displaying. Sleep light doesn't blink indicating sleepiness.

Any help on this would be greatly appreciated :)
