A possible problem with Lion is not technically with Lion itself. When 10.7 is installed, there is an additional partition created called Recovery HD, which contains a minimal system for booting a limited environment. Because of this, out of the gate you have at least three partitions: sda1, sda2, sda3. You can only add one more partition and have parity with a hybrid MBR and I'll bet gptsync does this incorrectly. And there are also 2.2TB concerns because of course the Windows partition can't go beyond the 2.2TB limit. So how the MBR should look in a triple boot, is unique. I've done probably 2-3 dozen installs and figured out one that's ideal for less than 2.2TB disks, and one or two that are tolerable, but still gross lies, for 2.2TB+ drives.

It also requires giving up on the Windows bootloader and use GRUB2 for bootloading both Windows and Fedora.

Well that's completely bogus. I've heard this myth before, I don't know where it started. I think some traveling support crew probably were misinformed that rEFIt is an EFI firmware replacement, and if it were true that people were flashing Apple's firmware with some 3rd party firmware, they'd be able to void warranties. But rEFIt is not firmware, it's a set of EFI applications and drivers. So whoever says this is completely full of crap and doesn't know what they're talking about.

Apple doesn't care to support foreign OS's.
