Hmm. Which means I need to still make my own uboot+power46 image when I figure out how to either get or compile a mkimage binary for my N900 (or crack and do it from a Debian VM, but I like the aesthetic of making the kernel image onboard the N900).

Nevertheless, thank you for providing this. It makes me happy to have the uboot screen back, even if I'm not dual booting regularly - just so that I can have it when I build up the motivation to learn how to partition drives/(other-name-for-all-computer-storage-media) correctly.
