It was working perfectly fine for me on a karmic setup with grub2 as
boot loader.

I think the problem in your case is improper lines in 40_custom. For
example, everything from 'linux (' to noprompt should be on same line.
Also those two dashes '--' should be removed.
Try these changes and report back.
