btw: I have a similar problems, but not with the boot disc, but one of
my data drives, thus I want ata_dma enabled for the other discs.

I have to dispatch a

    atacontrol mode 1 foo UDMA33

to set this drive (slave on second controller) to UDMA33 (otherwise it
would use UDMA100). But I have to do it before /etc/rc.d/fsck starts
accessing the device. Right now I've added above line to the beginning
of aforesaid script.
Is there a nicer/better place to tell the kernel (don't like editing the
rc-scripts).

Best regards
 Christian
