After udevd starts, udevadm might shed some light.
I tried "udevadm trigger" but that didn't help.
I tried your initrd & kernel with the patched qemu:

Can anyone give me a hint what might be missing here? Do we need to
implement modlias_show and _hotplug [3,4] for falconide [5] or are we
missing something else?
Probably something else. There is already a .uevent method with a call
to add_uevent_var() in drivers/ide/ide.c.
Hmm. Do we maybe need additional generic modules to be loaded?
The SCSI CD-ROM requires cdrom & sr_mod. I don't know about IDE.
