can you try to do rmmod ehci_hcd rmmod ohci_hcd and see if you can then suspend ?
I tried rmmod ehci_hcd - and then it could suspend. Interestingly after the first suspend - the following worked: - " modprobe ehci_hcd ; echo 3 > /proc/acpi/sleep" I've also tried kernel-2.6.6-1.397 - the same behavior - except for the last part. I had to remove ehci_hcd for subsequent suspend as well.
Just duplicated this on IBM R50p running FC2 with latest errata kernel 2.6.6-1.435. Logged into X as myself, xterm as root. "echo 3 > /proc/acpi/sleep" failed to suspend. I tried "rmmod ehci_hcd" and "echo 3 > /proc/acpi/sleep". It suspended, but when I hit the power button, it came back to a Fedora login screen.

mass update for old bugs: Is this still a problem with the 2.6.9 based update kernel ?
ACPI suspend/resume works fine with 'FC3/kernel-2.6.9-1.681_FC3' (without 'modprobe -r ehci_hcd') on the T40 (however I mostly use APM instead of ACPI) This issue can be considered resolved
