| It's all in the kernel .config:
| CONFIG_BLK_DEV_IDEDMA_PCI=y
| CONFIG_IDEDMA_PCI_AUTO=y
| CONFIG_BLK_DEV_IDEDMA=y
| CONFIG_BLK_DEV_ADMA=y
| CONFIG_IDEDMA_AUTO=y

...and then use a bootup script to execute hdparm? At least I found that
necessary.
You can use
$ hdparm -tT /dev/hda
to test the speed of your hard drive. Before using the bootup script, I
was getting a throughput of about 5 MB/sec for buffered disk reads.
Now's it up to 28 MB/sec, and I can feel the difference :-}.
