Fix NV4x flicker and irregular brightness progression. #49

Closed iam-TJ closed 12 years ago

iam-TJ commented 12 years ago

The original code used 16-bit I/O reads and writes to the smartdimmer
register. The Nvidia registers are 32-bit and should be addressed using
32-bit I/O operations on a word boundary

Use io{read,write}32() and adjust the register address and mask accordingly.

This patch finally fixes the constant flickering, and the level glitches when adjusting levels. It's now smooth and consistent on the GeForce Go 7600 (NV4B).
