Entering the BIOS isn't really a Syslinux situation but more of the
OEM/BIOS vendor.  However, I may have some suggestions.

Watch the keyboard itself for initialization.  With machines with PS/2
and USB support, I've noticed PS/2 keyboards initialize sooner and
sometimes USB keyboards aren't usable for pre-OS operations.  With
USB, I've noticed some machines either don't initialize USB keyboards
behind a hub fast enough, to enter the BIOS/firmware configuration, if
at all, for pre-OS operations.

Good luck.  In general, I count on needing to replace random parts and
maintain a spare parts supply for PC equipment over 4 years old.
