Udev is playing tricks on you. The kernel you compliled recognizes
things in a different order, and udev gives them different names.
Use e2label to give your root file system a volume label, e.g., root-fs.
Edit your /etc/fstab and /boot/grub/menu.lst files. Replace
"/dev/sda3" with "LABEL=root-fs"
Make a new initrd image with the new /etc/fstab in it.
Let us know if that solves the problem.
