Some of the newer Radeons (R420 for example) have MM_TABLE's with size 0x33
    (instead of 0x0c that we know). Furthermore, they lockup during access
    of I2C bus !
Add a check to validate MM_TABLE. Note: the check is not more stringent as
    other card manufacturers (like Asus or Tekram) might make cards with
    slightly different MM_TABLE.
