What will happen when a PATA disk lies behind a Marvel(ous) bridge, as

Larger transfers work fine in PATA, too.
WRT bridges, it is generally the best idea to limit to UDMA/100 (udma),
but larger transfers are OK.
Is large transfers mandatory in the LBA48 spec and is LBA48 really
mandatory in SATA?
Yes and no, in that order :) SATA doesn't mandate lba48, but it is
highly unlikely that you will see SATA disk without lba48.
Regardless, libata supports what the drive supports. Older disks still
work just fine.
