In i8042.c i8042_controller_selftest() gets also called after
suspending: So give it a try and add "i8042.reset=1" to your
kernel-parameters. If that works for you, add your device to the
i8042_dmi_reset_table in i8042-x86ia64io.h or tell us the output
of:
cat /sys/class/dmi/id/product_name
cat /sys/class/dmi/id/sys_vendor
