Two Thinkpad 600 FreeBSd 2.2.8 users have reported that suspend works wven when cards are present.

I am not qualified to make such a judment. Rather, I trust your judgment and will send FreeBSD 2.2.8 apm source code in private mail.

This seems originally came from CONFIG_APM_ALLOW_INTS in linux. I had to disable the cli, otherwise the machine would not wake up.
