As it happens, I'm having a related issue. Boot a junker to Gentoo, 2.6
kernel, and the drive is "blacklisted" for DMA; boot same machine to
Knoppix cd w/2.4, and DMA enables on hda - and it makes a difference in
hdparm -t (4.?MB/s vs. 7.?MB/s). The story is that if I were to back
down to 2.4 or whatever to get around the blacklisting, I'm courting
danger to the filesystem unless I can update the drive's firmware.
