Great!  I've been wanting NetBSD/evbarm running under QEMU for some time 
now, so this is *really* fantastic.

I was able to get it running with NFS root, though there are still some 
networking glitches (dhcpcd didn't work properly, even though the kernel 
got an address)

Some brief tests indicate it will be a good platform for its intended

I'm happy to work with you to get this code into the tree;  I haven't 
had time to fully review it yet, but I did confirm it works.  :)   I'll 
contact you off-list.

Thanks again!
