Don't mix up controllers with channels:

Your controller supports two channels, which are called primary
and secondary channels. Each channel supports one master and one slave
device.

So the first IDE-controller controls hda - hdd
second controller: hde - hdh

...

Just found this:

cat /proc/ide/piix (piix only valid for piix-chipset here, look what
you have got there ...)

gives you infos ... this is kernel-info, straight from the heart of
your system ;-)

the /proc/ide tree gives you loads of valuable infos (all the /proc
does, BTW ...)

Maybe detect first if your system works fine. Which 2.6.x-Kernel is
it?

(You can contact me off-list as this is getting VERY offtopic ...)
