Well, this one seems to work correct. I can get around ~18MB/sec,
which seems to me normal. It will be nice to have this in 2.4.18. ;-)

[root@pidaibm david]# hdparm -Tt /dev/hda
/dev/hda:
Timing buffer-cache reads: 128 MB in 2.02 seconds = 63.37 MB/sec
Timing buffered disk reads: 64 MB in 3.49 seconds = 18.34 MB/sec
