SubjectIDE-DMA strangeness (another one)

I've just moved my IDE disks around, taking out an old
disk and moving my new 6.4GB disk from hdd to hda.

With this move I saw in improvement (hdparm -t) from 3
to 8.4 (!) MB/second... Now I wonder what kind of bug
in the Linux I/O subsystem could hold performance back
_that_ badly.
Of course both benchmarks were done on a completely
unloaded IDE chip/PCI bus...
