I can confirm this bug with Ubuntu 2.6.24-16.30-generic on a Samsung X20 laptop. The workaround mentioned, i.e. putting the line
SUSPEND_MODULES="ehci_hcd"
in some file in /etc/pm/config.d/ works, however only when suspending using the kde-guidance-powermanager applet. It doesn't work when pressing the sleep button. Probably the sleepbutton-event is still handled by the old scripts in /etc/acpi ?!?
