Listen guys, you are way out on a tangent.  There is >one< place where
we need to care about the geometry we use:  The boot-block.  We can
use any geometry we like in the kernel, as long as we have our
partition boundaries the same places.  This config will work just
fine, the trick is to >uncouple< our devicedrivers from the bios/mbr
view of things.

I don't have the code to do this right now, but I belive I know what
it takes to do it...  And yes I'll try before 2.1.
