Ok, all working. I reflashed the software to start anew, then install my kernel with framebuffer support. Then installed the power kernel, then installed the NITDroid kernel. So now I have a tri-boot system that can boot Fedora 12 with XFCE desktop, Maemo, Maemo Power and NITDroid. Hats off to the makers of Multiboot, it is a kickass bit of software. Well done and thanks!
