Ok, so with some quick tips from the nice peoples here in the list, I
was almost instantly able to track down the culprit to my hard draive
whackiness. It's my ATI IDE controller:
00:14.1 IDE interface: ATI Technologies Inc Standard Dual Channel PCI
IDE Controller ATI
In the kernel, I found:
Device Drivers --->
ATA/ATAPI/MFM/RLL support --->
<*> ATI IXP chipset IDE support
I built this into my kernel, and now I get:
hdparm -tT /dev/hda
/dev/hda:
Timing cached reads: 2860 MB in 2.00 seconds = 1429.91 MB/sec
Timing buffered disk reads: 174 MB in 3.02 seconds = 57.54 MB/sec
That looks a HECK of a lot better!
I tried turning on DMA, but that didn't seem to make a difference.
Thanks to all for your help!

Han Solo:
Well Princess, it looks like you managed to keep me
here a while longer.
Princess Leia:
I had nothing to do with it. General Rieekan thinks
it's dangerous for anyone to leave the system until
they've activated the energy shield.
Han Solo:
That's a good story. I think you just can't bear to
let a gorgeous guy like me out of your sight.
Princess Leia:
I don't know where you get you delusions, laser brain!
Chewbacca laughs
Han Solo:
Laugh it up, fuzzball!
