eCos - it's an embedded system used in the real world, so it's not super simple, but since its aims are less universal, there is less code and therefore it's easier to follow what's going on.
Minix - this has really clear, readable code. I once needed a floppy driver for eCos and ended up porting the minix code, because the Linux and *BSD drivers were so hairy.
