Ah yes, it still seems to be "udevinfo -a --name /dev/hda" with Lenny's
udev.

The output should not stop here, it should go on "upward" to the IDE
controller. Also, I had expected to see something like
'/devices/pci0000:00/0000:00:09.0/devices/ide0' instead of just
'/devices/ide0'. It looks like the controller chipset is not recognized
properly, and the amd74xx driver is not used.
Hopefully there will be an error message somewhere that clears this up a
little. Try to reboot and then run:
dmesg | grep grep -Ei 'ata|ide|amd74xx'
Furthermore, there could be relevant messages very early in the boot
process; you might have to use ScrollLock plus pen and paper to catch
them (or set up logging to a serial console).
