I think the write to mtdblock3 didn't work. Although it didn't report an
error when I added the seek=3, it still read back the old data. So
you're right, I hadn't removed the amstrad LDR.
In the end, I re-arranged the mtd partition table and moved mtd3 down by
1M and built a new kernel. That fixed the problem (once I found the post

So now I've got my E3 booting of the nand :-)
