Actually, on my T41, FC5 is the first release to suspend/resume correctly 
right out of the box (modulo an issue with powering off the graphics chip 
that's been around for a while and has a known workaround).  But I can 
think of a few points to consider.  For one thing, I'm running GNOME.

Were you using APM or ACPI in FC4?

Did you update from FC4 or do a fresh install?  Do you have pm-utils 
installed?

What's your video card?  Are you seeing the machine indicate that it's 
suspended properly but just stay hot and drain the battery?  What part of 
the machine stays hot?

Are you logged in when you suspend?
