Always get COM32 modules from the same package.  You're using
vesamenu.c32 from a release before 4.00 with PXELINUX 4.02.

Also, as far as grep'ing or searching the hard drive, you should
consider writing a COM32 module like the ifcpu.c32 module to run one
command/LABEL if installed and another if not installed.
