Thinkpad 600 + FreeBSD 3.4-RELEASE + generic PAO3 kernel.

Update: the premature wakeup happens only when a pc card is present. When no card is present the machine suspends as expected. For example, the machine wakes up prematurely when one of these cards is present: IBM ethernet card (no cable attached) or ZOOM modem (no cable attached). I have not tested other cards. Could it be that disabling a cards somehow generates an interrupt that triggers the premature wakeup? Inserting/removing cards all the time would be be rough on my machine, and would be inconvenient when testing network software. Below are a couple fragments from the messages file. Wietse Messages logged after closing the lid with modem card present. Disabling the "PCMCIA Modem removed" message in pccard.conf does not make a difference.
