One somewhat ugly way to do this would be to re-purpose the NVRAM's 
"filename" setting.  Then you would embed the following gPXE script:

#!gpxe
${filename}

gPXE could be de-activated when the "filename" setting is set to 
"exit".  It would be active if it was set to "autoboot".

You might also consider the gPXE mailing list at
