The responses to my questions have been overwhelming... So I guess I'll 
debug it myself.

Here is the syslog (attached file Kernel-001.log) when loading just the 
ide modules thusly:

echo Installing ide modules
insmod /lib/ide-core.o
insmod /lib/ide-disk.o
insmod /lib/piix.o
insmod /lib/ide-detect.o
echo Installing scsi modules
insmod /lib/scsi_mod.o
insmod /lib/sd_mod.o
insmod /lib/aic7xxx.o
insmod /lib/ide-scsi.o
echo Installing usb modules
insmod /lib/usbcore.o
insmod /lib/ehci-hcd.o
insmod /lib/usb-uhci.o
insmod /lib/usb-storage.o

Note that kernel parameters idebus=66 and hdd=ide-scsi are not applied 
and that "ide0: ports already in use".

Cannot probe hda or hdb
