Mac Pro, Debian/OS X dual boot, EFI - I'm missing something

I've been trying a while to get linux running on my Mac Pro (Intel, not powerpc). Specific model is MacPro1,1. I tried just installing Debian alone, but couldn't get it to boot alone or with rEFIt. Others have suggested keeping OS X on the system for Apple updates and now I'm trying that. I've read a lot on the web and have been mostly working from this page:
I have Debian stable successfully installed (I'm working from it right now!). I'm using rEFInd, an updated/maintained version of rEFIt also described on the pages above. (I'd be happy to hear if people this rEFIt is preferable for some reason.)
During Debian install, it tries to run grub. I have a bios partition waiting (/dev/sdc99). By default, it tries /dev/sda and fails. I tell it /dev/sdc and it completes without error. Looking at aptitiude right now, grub-pc is what is installed.
Following the steps on the page above, once linux is installed and your using protective MBR, not hybrid MBR, (The author of the page argues that protective is much safer than hybrid MBR.), you boot from a CD with grub on it (http://www.supergrubdisk.org/). When I do this, I get a list of things for grub to do and one of them is find grub.cfg and run. Well, it does find what I assume is a grub.cfg from my Debian install. It doesn't work by default, but if I edit it to boot from (hd1,gpt4) it works. For some reason, the cfg or something has (hd2,gpt4). /dev/sdc4 is my /boot partition. When I edit it to hd1, it boots and starts Debian. (I am editing this using i3 and xrandr with dual heads without a glitch!)
So, I'm very happy to have gotten this far. What is the proper course forward to get it to boot automatically? I'd rather not have to boot from the supergrub CD all the time. I assume I need to switch over to grub-efi, but I tried that yesterday and lost all access to my linux partitions.
Any pointers, thoughts, experiences, etc. will be greatly appreciated! Thanks for your time!
