No.  I changed the /dev/sdX device names to uuid udev aliases in
/etc/fstab, /etc/lilo.conf, and /etc/initramfs-tools/conf.d/resume
prior to issuing "update-initramfs -uk all".  And these alias
names should exist in the -3 kernel too.  As an example, I changed

   /dev/sda1

to something like

   /dev/disk/by-uuid/04db5929-51e6-424a-ac5b-a592b96b9d04

udev under the -5 kernel creates a symbolic link by this name to
/dev/sda1.  udev under the -3 kernel creates a symbolic link by
this name to /dev/hda1.  Or at least it should.
