>From my reading of the source, vendor-option 134 is only parsed by the
nfsclient bootp code which is activated with the BOOTP kernel option.  If
you want to use that feature via PXE then pxe_open() in
src/sys/boot/i386/libi386/pxe.c needs modification, specifically to parse
the array in bootplayer.d.

pxeboot passes its information via kenv and would require a bit of code
hidden somewhere to convert it into a sysctl to maintain compatibility
with the BOOTP feature.
