Shove NITDroid on mmcblk1p4, and add u-boot to power48. When you get to the u-boot screen, run noloboot, then from there, you're in the multiboot screen. Go crazy. Oh, and on the multiboot screen, you need your Maemo kernel to be an image WITHOUT u-boot. And you need a Maemo/MeeGo kernel image WITH u-boot. Yes, it's a cluster****. But until NITDroid moves on to the superior u-boot, it's going to stay a cluster****.
