triple boot on macbook

my macbook specification:
mb881kh/a white macbook 09 early with 9400m graphic

my goal : opensuse + mac os x + windows xp with sp3

i tried instructions for macbook in howto document.
but i can’t install opensuse on my macbook.

  1. i downloaded installation dvd and live cd.
  2. i downloaded rEFIt and installed it on this machine.
  3. made room for windows with bootcamp as wiki said.
  4. rebooted and held down ‘c’ key for cd boot.
  5. opensuse install menu appeared on my screen.
  6. chose to install opensuse.
  7. installer made some progress but soon stopped working and proceeding… green or black screen showed up…

what was wrong with my try? of course i updated leopard to 10.5.7 version.
