If i don't mistake the original gfxboot patch did only implement gfxboot for
syslinux and isolinux. The gfxboot COMBOOT module does work with syslinux,
isolinux and extlinux. The cb_fopen callback from gfxboot core does expect file
length in ecx. I did assume pxelinux can not return the file length on file open, tho
i did not verify it.
