You can use a script similar to the one I have shown in this gist,
https://gist.github.com/911561, to set the pxelinux prefix and config
location explicitely in the script.

Be aware though, that it seems like there is no way to modify the prefix
and config location at a later stage in the PXELinux process (to e.g.
forward the user to another pxelinux server with a specific
configuration from a PXELinux menu entry). But if you're using a
monolithic PXELinux menu it shouldn't give you any problems.

If someone knows a way to do what I want, please do tell me!
