I've tried Ubuntu patch but does not apply cleanly, probably is old... I've applied insted the RH one (plain patch on:
http://pkgs.fedoraproject.org/cgit/cdrkit.git/plain/cdrkit-1.1.9-efi-boot.patch ) and recompiled cdrkit 1.1.11-3 sources: compile flawlessy and works as expected. Please, add this patch!!!
