You also don't need the server IP in option root-path -- you can see 
diskless(7) for more info on that.

It's possible I have broken building a 32-bit world, so thanks for 
pointing that out.

That is very odd and should not happen. I'll look into it.

Also, you asked about memory above 2 GB. It should be recognized and 
should work, but using DMA to that memory will likely fail in 
interesting ways since some bus dma support bits are not yet implemented.
