Details

The "psmouse" kernel module is known to cause problems with some newer laptops, e.g. sudden poweroffs when resuming. Arch therefore already explicitly unloads it in /etc/rc.d/rc.shutdown. However, this isn't done with pm-utils before suspend or hibernate.

Arch could supply a config file in /etc/pm/conf.d with the module noted since pm-utils has a facility for removing modules before entering suspend or hibernate.
This task depends upon

This isn't something I care to implement, given that it affects only some users and that pm-utils provides the framework to address this very issue on a case by case basis. For example, my USB hub doesn't reinitialize the devices connected to it after a resume, so I've added the following to /etc/pm/conf.d/usb-workaround:

# reload the following modules to fix USB issues
SUSPEND_MODULES="ehci_hcd uhci_hcd usbcore"

It's just as easy for other users to do the same if they have finicky hardware.
