    But it was an invalid test of seeking, it was testing track-to-track
times, which won't get any better...

    Try this: [I don't have the chip installed yet so I can't]

        dd if=/dev/swap of=/tmp/woof bs=512

Note: Do NOT use a large buffer - the idea is to make it seek a lot.
This way (w/512 bytes) it will seek there for every sector, the ideal solution
I would presume.  It should be easy to test this using the driver idea that
was just posted.
