i will like to help in this. Silicon Motion is still having SM712 in its product line and SM718 might also be a similar one.

now the problems (as i see) for me to help in the driver :
1) i am a newbie. though i have learnt a lot from the patches i sent , but still I am a newbie.
2) most important - I do not have the hardware. So from the TODO list dual head and 2D acceleration support will be tough without actually checking on the hardware.

thanks
