Read this page and the next few after it for the very small bit of work done on it.
I've been extensively looking into if porting mdnie to the N10 is possible from a different device (in this case the Note 10.1) and I think it should be very possible. I've been comparing the mdnie implementation they've used on the Note 10.1 and Nexus S as they use different frame buffers (Note 10.1 uses S5P and Nexus S S3C). As I have no prior knowledge of frame buffers, I was surprised to find that S5P and S3C look pretty much the same on these two devices. As the drivers looked pretty much the same from Nexus S to Note 10.1, I think there's a chance they could work straight away (or with very slight modification) on the N10 which would mean that porting mdnie could possibly be (if we are lucky) as easy as copying over the drivers and changing in the config files.
If someone with more skill wants to take a look at this, the files you need in the Note 10.1 sources are located in drivers/video/samsung/ and they are
s3cfb_fimd6x.c (not completely sure if this one is needed)
I would probably try doing this myself but something tells me that flashing a kernel with a frame buffer that might not work could cause me some headaches
