To clarify, this client can successfully tftp the pxelinux.0 file over 
when configured for legacy BIOS mode?
I agree that the "client does not accept options" message is not an 
issue as I see this also as part of the tftp connection negotiations.
I also confirmed that my files are 644 and owned by root so that is not 
the issue.

This looks suspiciously like a config problem on the server 
(firewall?).  You can troubleshoot the issue using a tftp client on one 
of your test boxes.
- install a tftp client if you do not have one already

this should get the file successfully.  If it does not then you can look 
at the logging on both sides.  Also, if it does not then try "get 
fai/pxelinux.0", which is the BIOS boot file and was working for you.

Not an answer but I hope this helps.

Cheers,
Merlin.
