Thanks! The key (mentioned in the documentation there) is to disable
framebuffer (ATI video card). First time I've had suspend-to-RAM working
on this machine. ;)

Suspending works with `s2ram -f`, no other options needed, from X.

# s2ram -i
This machine can be identified by:
sys_vendor = "Dell Computer Corporation"
sys_product = "Inspiron 5100 "
sys_version = ""
bios_version = "A23"

Though you may want to rename the /usr/sbin/suspend command to something
other than 'suspend' as, at least for me, it is a shell command which
puts the current shell in the background.

The HOWTO *does* mention:
[Warning: some shells have "suspend" built in command, so specifing
exact path like ./suspend is more important than usual.]

Though I still believe it'd be a good idea to pick a non-conflicting name.
