Got one of those, works fine. How is it connected to the motherboard, on
one of the builtin ide channels, or on the supplied card ?

it's a "82371AB PIIX4 ACPI".

it's a USB controller, "82371AB PIIX4 USB" to be exact.

IDE interface, "82371AB PIIX4 IDE"

ISA bridge "82371AB PIIX4 ISA".

Ahh, the chipset device, "82439TX". You've got a TX motherboard, and
those didn't exist when 2.0.30 was released (well not so as the kernel
knew about them anyway).

Hmm, the kernel should still find it if it's on a builtin ide channel, if
it's not you'll have to tell it where the IDE "controller" is. For
windows driver brokeness reasons (the looks on there ide "controller",
and then desides wether to install the ide support), mine is on the
supplied card, and I tell the kernel about it with this in my lilo.conf:
append = "ide2=0x1e8,0x3ee,11"
The double quotes are important. Read the correct settings off the board
for the first io and irq, no idea where the second comes from (well
linux/Documentation/ide.txt, but ...), that's the "official" third ide
adapter settings ;).
