optimized DMA acc code more by splitting up command lists into sublists before issuing them to the engine. this further improves speed with upto about 70 percent, for a total of about doubling the speed by pure software optimation.
Note: code is now working the same as Thomas's ATI driver: he minimized calls in the same ways. (Curious how a benchmark contest would hold up now.. ;-)

applied DMA mode speed optimations 'step 1.5': incorporated all top-level acceleration functions inside the engine's code so minimal nested calls are made. Confirmed further speedup of about 15% on fast CPU's...

added a nv.settings switch 'dma_acc'. User can choose method for acceleration. Default is off, selecting (old) PIO mode. DMA still does not work, and is not completed.

added cursor HW bug workaround for NV40 and higher on CRTC1; added seperate acc file for DMA test setup for NV40 and higher (for now).
The driver now works by default on NV40 and higher, but without acceleration.
If someone tests using overlay, let me know if it actually works: NV43 seems to have a new engine, NV40 _might_ still have the old, and so, useable engine.
NV40-plus overlay is something we will NOT have any time soon!
