This patch:

   - Makes the cdc code handle a Motorola cable modem that stores
     CDC descriptors in the wrong place.  The workaround might be
     helpful for other hardware too.  (This was a 2.4 regression.)

   - Recognizes another Zaurus (PXA 255 based clamshell, not yet
     sold by Sharp in the US).

   - Cleaned the Zaurus stuff up a bit.  Rather than expecting
     a new driver_info struct (or re-using the right one) for
     each new pxa based product, they all use the same one.  So
     patches for new products only need new usb_device_id entries.
     (Also notes the issue that every Zaurus model will need to be
     blacklisted for CDC if the Z code isn't enabled.)
