Add missing id_table to the drivers in subject. Patch is against the
latest git. It should go in with 2.6.28 if possible, the drivers won't
work without the id_table bits.

We now read and write the century byte in the max6900 chip. We probably
don't need to do so on Linux-only system, but it's necessary when the chip
is shared by another OS that uses the century byte.
