Yes, and I keep pushing it forward because of the restructuring you're
doing =) (feel free to comment on that thread). But agreed, it's getting
better. When we have manual update support, I think the biggest missing
feature is then in omapdrm.

Considering how much headache TILER has given, I'm not exactly looking
forward to it ;).

If we get manual update and VRFB, I think we are more or less covered on
the supported HW features. It'll still break userspace apps which use
omapfb, though. Unless we also port the omapfb specific IOCTLs and the
sysfs files, which I believe we should not.
