Are the other servers also VirtualBox, or real hardware?  What toolchain are 
you using?  (gcc version, ld version, syslinux version)?

It's not documented anywhere at present, but if you enable VLAN_CMD in 
config/general.h then you should see "VLAN" appear within the iPXE feature list 
at startup, and you'll have two extra commands available: "vcreate" and 
"vdestroy".  For example, if you wanted to always boot from VLAN 12, you could 
embed a script such as:

  #!ipxe
  vcreate --tag 12 net0
  autoboot net0-12
