That really does appear to be the problem here, and I'm thinking the best thing to do might be to walk through the code and figure out how and where it's supposed to be doing this and doing enough tweaking on a test version of iPXE that we can see if this code path is actually being followed, if indeed it even exists at all.

Yes, but ipxe skips the 4011 stuff when boot info has already been received. In your case, as option 43 on port 68.

Basically, some proxy DHCP servers use option 43, others use port 4011. A few do both.
