I patched syslinux a while back to allow loading and passing a DTB to
the Linux kernel. Patches based on that work went into syslinux 4.06
IIRC. Note that currently onle the linux.c32 executable contains that
functionality but there were plans to make it available in the standard
loader in 5.00 I think.

Alternatively you could customize OpenFirmware for your device. OFW can
be built as a COM32 executable and can be run from syslinux or it can be
used as a BIOS replacement.
