I am running Fedora 8 on a ThinkPad Z60m (model 2530-38U), and I see that /usr/share/hal/fdi/information/10freedesktop/20-video-quirk-pm-ibm.fdi mentions Z60m in a comment for the S3 quirks, but my product ID (2530) is not listed in the match list. Adding 2530 to the list allows suspend/resume to work correctly.
This is also filed in Red Hat's bugzilla at: https://bugzilla.redhat.com/show_bug.cgi?id=425875
