I don't have a Sheevaplug, I have a Dockstar which is similar. So I
don't know exactly how to help you.

However, if you search on netbsd sheevaplug boot, I think you'll find
interesting info.

If you build a Sheevaplug kernel, you should get something called
netbsd.ub which is uboot friendly. I believe you can tftp boot it or
boot it from a FAT partition.

Your command to boot the kernel might work if you use 0x2000000, given
that the kernel is uboot friendly.

In my case I have to hardcode the root device into the kernel, not
sure if you have to do that on Sheevaplug.
