Syslinux - Jun 2011 - COM32 module for detecting Memdisk?

I know there's a module to check which syslinux bootloader was used, but 
is there also a module for detecting MEMDISK?

Basicly I want to use the same isolinux.cfg for a CD which boots an ISO. 
Issue is that the inner ISO also uses same Isolinux (+ menu), which 
isn't very user-friendly.

So:

CD --> ISOLINUX (menu) --> MEMDISK CDROM.ISO --> ISOLINUX (menu) -->
diskette image.

It would work in the same spirit as  the IFPLOP module I guess:
IFMEMDSK.C32 FDOSBOOT MENU.C32
(execute label FDOSBOOT if ISO was booted through Memdisk, otherwise 
present the menu.)

Does such a module make sense?

Is there a reason you cant load the diskette image from the first isolinux menu
using the memdisk kernel?
