try the following after resume (maybe from your USB keyboard :-)
as root:
#!/bin/sh
for i /sys/bus/serio/devices/serio*/drvctl; do
echo -n reconnect > $i
done
--------------------------------------------------------
or, if this does not help, before suspend do:
echo -n "i8042" > /sys/bus/platform/drivers/i8042/unbind
(warning! the internal keyboard and mouse will stop working immediately!)
and after resume:
echo -n "i8042" > /sys/bus/platform/drivers/i8042/bind
If this helps, report it to the linux-kernel list, and put the workaround
in the wrapper that triggers suspend (probably pm-utils nowadays)
Good Luck :-)
