I was running through the low-latency howto and I ran

First off, I'll mention that I'm using a Dell Inspiron 2650 laptop.
I'm running debian unstable with 2.4.19.
1) DMA transer won't enable. I've enabled DMA transfers in the kernel
as suggested by the howto. However, I'm unable to turn on dma access
with hdparm. I'm told the operation is not permitted.
I have a 2650 and it appears the dma problem is a bug in the 2.4.18 kernel
with certain IDE chipsets. Apparently fixed in 2.4.20
