The acpi man page (FreeBSD 7.0) says S3 is supported, but S4 is only supported in hardware with a BIOS that supports it, which these days is rare. My experience is that even S3 support is iffy. My Dell laptop is perfectly happy to suspend, it just never wakes up after that! As soon as my Fujitsu laptop arrives this will be a top priority. The lack of reliable S3 makes a laptop next to useless to me.
