I could be wrong but I think that the special patches are actually 
directly related to extlinux. Anyway, as you said, if you are using 
official upstream code, the ones in YOCTO/OE should not matter (except 
that all Syslinux-related files should come from the same build).

OK, so SYSLINUX itself is actually booting.

Let's try a (hopefully) "better" syslinux.cfg:

#***syslinux.cfg***
# Labels should not include white-spaces.
# Even better when labels are limited to 8 characters or less.
# When testing a Linux kernel, better to use the LINUX directive.
DEFAULT syslinux_yocto_test
LABEL syslinux_yocto_test
LINUX /boot/vmlinuz
#******************

Let's try again and report back.
