I've found an easy way to introduce a graphical isolinux menu in MCNLive, navigation with keyboard:

Much easier than the ugly gfxboot suse/novell patch :-)
Found it on the new Fedora live and the syslinux site. Using the plain isolinux.bin with a vesamenu, and a 640x480 jpg file as background.
The normal isolinux.cfg is all that is needed as config.

MDV did it again and preferred a patched syslinux package instead of using the unpatched syslinux/isolinux. And they don't ship the vesamenu.c32 in their rpm.
The fedora ones do work, though, even on a mdv 2007.1 system :-)

The link for syslinux-3.36-5mcnl2007.1.i586.rpm is no longer any good.
Don't suppose we could get a link to it.. or the location of a repository.
I've tried several Contrib sources only for urpmi to tell me it doesn't exist.
