Yaboot not recognizing volume labels

[Dustin N. Jenkins]

I'm running an unstable 5.0.3 on a 15" PowerBook G4 on a custom 2.6.32.3 
kernel.  I have a single partition that is a reiserfs file system.

When I tried to upgrade to a 2.6.32.4 kernel (or higher as the current 
stable kernel is 2.6.32.7), I got the "Waiting for root file system..." 
hang.  Debian has some documentation about it:

http://www.debian.org/releases/stable/powerpc/release-notes/ch-upgrading.en.html#boot-hangs 


I tried the suggestion of labeling the file system to 'Root', but it 
still hangs.  I thought maybe the initramfs image wasn't being setup 
properly, so I modified the /etc/initramfs-tools/initramfs.conf file and 
set this:

ROOT=LABEL=/Root

and rebuilt my initrd.img:
mkinitramfs -o /boot/initrd.img-2.6.32.7 2.6.32.7

The resulting image was 22MB, and the system still hangs.  If I try to 
configure my /etc/yaboot.conf to look for the root at LABEL=/Root, it 
becomes unreadable when selected at the Yaboot selection screen.  I have 
also tried to set the root to /dev/sda4 instead of /dev/hda4 as per the 
suggestion in the Debian documentation above, but it still hangs.

Here is my current yaboot.conf (The 'old' image boots fine):

boot=/dev/hda2
device=/pci at f4000000/ata-6 at d/disk at 0:
partition=4
timeout=100
install=/usr/lib/yaboot/yaboot
magicboot=/usr/lib/yaboot/ofboot
enablecdboot
macosx=/dev/hda3

image=/boot/vmlinux
     label=Linux
     read-only
     initrd=/boot/initrd.img
     append="root=LABEL=/Root"

image=/boot/vmlinux.old
     label=old
     read-only
     root=/dev/hda4
     initrd=/boot/initrd.img.old

Any help would be appreciated!
Thanks,
Dustin
