Freeldr.sys and setupldr.sys should now be a multiboot compliant:

I downloaded the ReactOS bootCD and extracted it to the first partition of
an USB drive.

The following Syslinux config file, lets me start the ReactOS Setup:
UI menu.c32

LABEL reactos_setup
COM32 mboot.c32
APPEND /loader/setupldr.sys

mboot.c32 might need additional changes to pass the correct boot drive and
partition in the future.
