First off, I want to thank everyone who responded with suggestions
and comments. I was worried that I might get a lot of flames about
these test, and that's not what happened.
The most common suggestion I received was "use FreeBSD 4.8", so I
managed to make some time between the electrical storms today, and
my regular work to do just that.
Unfortunately (as you'll see) the results were _worse_ than with
FreeBSD 5.1.
I'm interested in two major things right now:
1 - can anyone suggest anything I might be doing wrong to get such
lousy results?
2 - Can someone please try the tests on SCSI hardware? I don't
have any SCSI systems available to test on, and I'd like to
figure out if it's the filesystem or the ATA driver that's
the problem. Hell, can someone try out the tests on some
other brand of ATA/HDD, to make sure FreeBSD doesn't just
have some grief with this particular piece of hardware?
The updated test results are the same place the previous tests
were:

I'm attaching dmesg from the test machine to this email, if anyone
knows of any problems with this hardware and FreeBSD, please let
me know so I can stop banging my head against this and just accept
that it's a hardware problem ;)
I was assuming that the "falling back to PIO mode" was because this
board didn't support DMA, but I'm beginning to wonder ...
