Yes, me. With a Slackware 9.1, FWIW. ;-)

I've had hangs with sleep, that were fixed by using
acpi_sleep=S3_bios. Hibernation always worked for me - with latest
ACPI patch, latest swsusp-patch and latest hibernate-script at the
time I compiled my kernel (which was Thu Oct 28 02:19)

Let me know if you'd like to get my kernel .config or any other information...

I chose ACPI because of the far better battery information. All the
other hardware/system information is much better than you can get with
APM, too (i.e. hotkeys, ThinkLight, processor temperature...)
