The openSUSE installation DVD will of course boot, having all the proper signatures that you needed to install the OS in the first place. And it will be booting the kernel present on the DVD, which is signed by the SUSE key.
In case you wanted to create your own rescue DVD that'd be booting custom kernels, that'll be possible, too, using the same shim loader you'll be able to enroll your MOK, or just use one if already present on the system.

Vojtech, would this apply to the current openSUSE 12.1 - or are you speaking about future releases that have all of this included?

Of course only about future implementation, we don't have any signatures on openSUSE 12.1 and thus it won't work with Secure Boot enabled.

Thank you for confirming what I suspected.
My apologies for using the wrong name for the CD I mentioned above, however I was wondering how a bootable CD such as the SystemRescueCD which comes from systemrescuecd.org (http://www.sysresccd.org/SystemRescueCd_Homepage), and similar bootable media, would boot under this UEFI process?
