When I said APM worked for me, that was in RH9. I tried the acpi=off
route (which appears to enable APM, which, in turn, allows the "apm"
command to work), but it simply does not work for me in FC3.
Here's a post I made to the linux-dell-laptops Yahoo! group with the
results of more investigation (all for APM, not ACPI):

I'm now lurching in another direction. The behavior I see is
consistent with a system that, after resume, cannot access its disk.
When the system resumes, I don't get a shell prompt immediately if I
hit newline, only if I hit Ctrl-C, as though I'm breaking out of a
shell script. I can poke around a little with shell commands until I
do something that, presumably, requires access to the disk. I can
look at files whose blocks are in the buffer cache. Once I go to the
disk, though, the system locks up.
Question: How can I tell whether the disk controller is alive after
resume (especially if I can't write anything to the disk!)? The disk
sounds like it spins up after resume.
N.B. I've looked at the HDPARM_AT_RESUME stuff in
/etc/sysconfig/apmd. I don't think it's appropriate for me to tamper
with those. First, suspend/resume had been working under RH9.
Second, I did an hdparm after resuming, and the values looked right.
=========
Any ideas here in c.o.l.p? Thanks.
