Subject: [PATCH] Fix a massive couple of botches here: the NVRAM settings read
 wasn't flagging the SYNC mode was enabled. The temp values for offset and
 sync period were uint8_t, but were being assigned and shifted from a uint32_t
 value.

This didn't show up in testing because a random number
of 1030 cards set a bit that says "honor BIOS negotiation",
which means this whole code path was skipped.

This should clear up at least some of the negotation
issues that have been seen.
