This I have no problem with. I'm willing to accept this. As long as data 
from the console layer is not touched. As for loadtiles one thing I like 
to address is memory allocation. It probable is good idea to do things 
like place the tile data in buffers allocated by pci_alloc_consistent.
The other fear is it will only support so many tiles. 

I think it's best to let the driver allocate it. That way the driver can put it
where it's best suited. pci_alloc_consistent() is meant for PCI only.

Sorry about the confusiing. I was meaning things like pci_alloc_consistent 
of course would be handled for each driver that needed it.
