Just for reference, my GPT disk boots fine on my ThinkPad with the following:

=> 34 1465149101 ada1 GPT (698G)

The disk has native 4K sectors, so the partitions are aligned
accordingly. That is why the free chunk at the beginning. the second
free chunk is due to my error which I'll get around to adding to p6
some day. I use traditional partitions (root, tmp, var, bin, and home)
and the home partition is GELI encrypted. (I I had hardware crypto
support, I'd encrypt everything.)
The disk does have the protective MBR installed, though it's not
really part of the GPT. (See the "GUID Partition Table" article on
Wikipedia for more information.)
