Some touchpads require reinitialization while resuming. See sys/dev/atkbdc/psm.c and look for PSM_CONFIG_HOOKRESUME and PSM_CONFIG_INITAFTERSUSPEND flags and some code arround PSM_RESETAFTERSUSPEND. usb2 stack seems to have resuming issues but I didn't care much about it because the stack itself is a moving target ATM. ;-) > HP6125 (UP) running kde4 suspends+resumes w/o any tweaks.
