Yes, it is possible but we would need an appropriate uboot for it.

But we don't need to do that, we can simply create a yaffs image (with
mkyaffs2) and write it to NAND.

I'd it working on RB450 once and it boots just fine. If i remember
correctly we can easily create a port for mkyaffs[2].

One thing that would be nice about the uboot is remove the 4MB limitation
for the kernel 'slice', but the good thing is that RouterBOOT can read a
gzipped kernel.
