let alipm0 still be used for spdmem probes, but skip sensors. alipm (or
more likely psycho) still has a bug where the pci bus croaks on the
intermittent i2c accesses. the spdmem accesses are safe, though.
if you wish to help us find out when this bug gets fixed, please run
your machine WITHOUT this diff, though.
