There are lots of problems with the PC centric view of the world some
aacraid hardware has.  At the moment I'm still working on trying to understand
the rules and I'll need to talk to Mark some more. I've also got a third
party trace suggesting a request for low DMA memory came in through the
gart which is above the address in the mask to look at.

Its something I hope to get rid of eventually. In the meantime the GART
define is needed to make it work on AMD64.

Its against 2.6.7
