Did you take into account that there may be an initrd that isolinux loads
after it loaded the kernel? The scripts can be run from linuxrc. 

isolinux has no idea under which device the kernel expects the cd-rom
drive - it uses the ones available from the bios, while the kernel may
be dealing with additional controllers (unsupported by the bios,
load the drivers in different sequence etc.pp).

BTW: This has almost nothing to do with syslinux/isolinux itself ...
