This is correct for uboot, though there are a few possible complications:
* Android will want to use 2 partitions, by default the first two, plus the
NAND. Then again it will (by default) install a forked Qi too, which doesn't
multiboot well anyway.
* Certain ext3 formatting options prevent uboot reading the partition, but I
haven't checked which ones. My gentoo box makes unreadable ones by default,
but fedora makes readable ones.

This is itself wrong, as I'm booting kernels from beyond the first 2G, and
probably beyond 4G.
