It may work fine for you, but sadly this isn't the case across the board.
The problem is that we don't have register level documentation for
nvidia chipsets (same story as their graphic cards), so we've no real
idea what we're doing, and the driver as it stands today is entirely
reverse engineered.
Given there have been upstream reports of instability with it loaded,
I chose not to enable it in the Fedora kernel to avoid seeing
undebuggable scenarios.
