Jarod,

I checked out the current setting, and found that dma was currently set to 1 (on)

using a 6.10 kernel in slackware I was able to get the following:

My box at work, latest FC3 kernel, single ATA-100 hard drive:

Timing cached reads:   2968 MB in  2.00 seconds = 1483.48 MB/sec
Timing buffered disk reads:   88 MB in  3.01 seconds =  29.21 MB/sec

Red Hat is more careful about disabling dma on potentially buggy chipset and
drive combinations, double-check that using_dma is set to 1 on your box.
