udev... have you followed the instructions in comment #7 of that bug report?
update to udev-030-7 and rerun mkinitrd

specifically what you want to do is make sure you have udev-030-7 installed
then you want to recreate the initrd for the kernel you are running.
example for 2.6.8-1.526:
  backup the old initrd image
mv /boot/initrd-2.6.8-1.526.img  /boot/initrd-2.6.8-1.526.img.bak
  create new initrd image for  2.6.8-1.526
mkinitrd /boot/initrd-2.6.8-1.526.img 2.6.8-1.526
reboot into .6.8-1.526

Make sure you have a kernel to fall back to before you do that
example. Or make sure you know how to edit your grub menu to use the
backup initrd...just in case something goes wrong with the new initrd.

Since initrd images on your system are created when you install the
kernel package, you
have to recreate the initrd image being used to take advantage of the
udev fixes that were created in udev-030-7 package.
