Not sure when the support was added but any recent GNU/Linux distro should support it. If you need to use Windows XP or earlier to access any of the partitions on the disk, then you need to stick with MBR. I don't know about Vista, but Win7 supports GPT.
One note however. If you are using a system with a bios, you need a special 2mb MBR boot partition and a MBR armored GPT table. That allows the bios to load the boot loader which then loads the initrd image that understands the GPT. This is the default in Fedora 16 when installing from scratch.
Also, you are better off using Grub2. Grub1 has no official support for GPT. 'lilo' should theoretically work, but I didn't want to tempt it.
And my statement was geared towards somebody who plans on upgrading eventually and just wants to toss the old hard drive onto the new system and want it to work.... Maybe I'm wrong on all of this, I only switched to GPT because I wanted to play with it and see if I could.
