Rename lgdt3302 to lgdt330x, to make way for the addition of lgdt3303 support in future revisions. I am changing the name of this module now so that hopefully the name will be changed before the release of 2.6.13 ... It wouldn't make sense to release 2.6.13 with the name lgdt3302 in it, which will only be renamed to lgdt330x in later versions.
