Yeah, different hardware tickling different bugs ...

On the TFTP server can you not just do
ln -s default b8945908-d6a6-41a9-611d-74a6ab80b83d
or
cp default b8945908-d6a6-41a9-611d-74a6ab80b83d
rather than playing with mapping files - just for testing purposes.
Have you tried pxelinux.0 instead of gpxelinux.0? Or possibly iPXE?

I was more thinking of seeing if the server responds at all - the
symptoms you see look like the server either ignoring the commands or
just not seeing them. I would suggest that a firewall is in the way
somewhere or wrong subnet or something like that, but as you say, it's
working for other clients.
