-* rename the offset definition to avoid abiguity with the standard ATA
-  IO address
-* read and write four bytes at once like the original driver does
-* use writesl() and readsl() which implicitly iterate over the data
-
-This patch assumes buflen to be a multiple of four, which is true for
-ATA devices. ATAPI support is not known, though unlikely, as the
-original driver always transfers 512 Bytes at once.
