Just another suggestion; and that is to get into the habit of using
explicit qualifiers inside of config-files, as documented in
syslinux/doc/sylinux.txt:

LABEL boothdd
  COM32 chain.c32
  APPEND hd1

I forgot that you (Matthew) originally wanted "LOCALBOOT".  Gene's quite
right about simply using the MBR.  However, if it won't boot, but has a
valid working OS installation _without_ the USB stick plugged in, you
might very well want:

LABEL boothdd
  COM32 chain.c32
  APPEND hd1 swap

swap
swap
swap is documented in syslinux/com32/modules/chain.c

"Swap" will make 0x81 (your HDD, if available) turn into 0x80.  Whatever
OS is on 0x80 might very well expect to be at 0x80.  Please try it.  Or
maybe I missed an e-mail and you have already tried it.
