Syslinux - Feb 2010 - INT 22H AX=000Ah, CL=9 and __syslinux_get_derivative_info()

comboot.txt says to set CL=9 "to get a valid return in CL for all
versions".
The code in __syslinux_get_derivative_info() doesn't set it. Is this comment
obsolete? Looking at comboot.inc suggest this because P_CL is set to
SECTOR_SHIFT
for all derivatives but pxelinux which does set P_ECX to MyIP.

hpa, can you please take a look at this?
I would like to use __syslinux_get_derivative_info() in gfxboot.c if there
isn't a catch.
