Thats what I expected.

I am doubtful that anyone still uses this driver.
With DRM framework support, I see very little use of this driver.

Also there are some hacks regarding buffer management, that need to be
fixed if at all we want to support it.

I would really want to slowly kill this driver, if no one uses it.

Thanks,
Vaibhav
