Fedora on Macbook Air?

I did some googling about this a while ago because a friend wanted to
single-boot Ubuntu on her Mac Mini. She got cold feet and stuck to her
dual-boot with rEFIt so the following is theoretical and from memory.

(1) You have to keep sda as a gpt disk.

***start***
# parted
(parted) print
[if "partition table" is not "gpt]
(parted) mktable gpt
***end***

(2) You have to move "/boot" to "/efi/boot" and it has to include a
"boot.efi" (unsure of the exact name) grub binary/stage loader. Take a
look at the structure of the Fedora 12 Live CD. (If you are booted
from it, the "ro" not the "rw" mount.)
