On my IBM 80 Go, 7200 trs/mn
Before : IO_support = 0 (default 16-bit)
hdparm -t /dev/hdd
/dev/hdd:
Timing buffered disk reads: 82 MB in 3.05 seconds = 26.89 MB/sec
After : IO_support = 1 (32-bit)
hdparm -t /dev/hdd
/dev/hdd:
Timing buffered disk reads: 74 MB in 3.03 seconds = 24.42 MB/sec
No changes seen....
