Yup, initramfs ;-)
You can try QtMoko v42 here:
it has one kernel which can boot from everything possible. SD and NAND/ubifs
boot options are builtin but you can provide scripts e.g. for booting from
squashfs image on mmcblk0p4 - whatever you want.
I will write longer mail about this later.

I think we can try 2.6.32 kernel how it works.
