I've booted the Dapper beta2 livecd and found the same problem. As before, lspci shows the IDE addon card later in bus order:

0000:00:08.0 PCI bridge: nVidia Corporation nForce2 External PCI Bridge (rev a3)
0000:00:09.0 IDE interface: nVidia Corporation nForce2 IDE (rev a2)
0000:00:1e.0 PCI bridge: nVidia Corporation nForce2 AGP (rev c1)
0000:01:07.0 Multimedia audio controller: Creative Labs SB Live! EMU10k1 (rev 04)
0000:01:07.1 Input device controller: Creative Labs SB Live! MIDI/Game Port (rev 01)
0000:01:08.0 RAID bus controller: Silicon Image, Inc. PCI0680 Ultra ATA-133 Host Controller (rev 02)

However, I think I've found the problem. Notice that the external PCI bridge comes before the nForce onboard IDE controller. In the udev log, it can be seen that the enumeration has a slightly different scheme, placing the addon card before the onboard controller:

PHYSDEVPATH=/devices/pci0000:00/0000:00:08.0/0000:01:08.0/ide0/0.0

The extra nesting seems to be the trouble? 0000:01:08.0 should come after 0000:00:09.0, but because of the 0000:00:08.0 it doesn't. Might this be the place to fix it?
