The initialization of the CMD PCI0643 IDE controller fails when using
the ESIEE kernel (which has support built-in for this chip).
Something like "failed to get IRQ, will probe later".

So no devices were found on the IDE bus, just on the LASI SCSI.
Probably it's the best just to use SCSI and not to use IDE support at all ...
