Second question I have is how are monochrome cursor images handled with KMS. Yes we need to support CLE266 which is used in a lot of POS devices. That chipset only supports monochrome cursors.
As far as I know, the KMS cursor API doesn't really care what type of cursors are supported. That's a client driver (ddx, etc.) implementation detail. The cursor interface just basically has on, off, and position. The client driver (ddx, etc.) can choose to upload a ARGB or mono image. We should probably add some sort of flag to KMS to ask the driver what types of cursors they support so this could be supported in a generic way.
That is the bit missing. I seen recently you had a patch for passing info to userland. It would be nice to add what color depths the cursor supports.
I think Dave proposed something like that for the generic KMS ddx.
