I am thinking the same thing.
If the unusual sg code is a problem, I'll think of something later to
improve it, heck I can even completely rip it off and just use kernel
pointers, relying on block core to bounce for high-mem situations.
Since its a driver for a legacy hardware, mostly provided for
completeness, the performance difference shouldn't be much.

I think its ok to merge the code with folded sg code _for_ now, and then
I will send patches to address this point you didn't like.

OK?
