Are there any plans on merging DirectFB features? Stuff like vertical
retrace interrupts etc.?

I wholeheartedly agree with this.  There are a lot of applications out
there (especially video players) where vtrace signal delivery is
critical for optimum operation.  Polling for VGA registers is not
totally correct for newer cards and is too inefficient, so this has to
be done at a per driver level.

Let me point out that the DRM in XFree86 4.3.0 and 2.5 kernels has a
generic ioctl which can block or send a signal on vertical blank
interrupts.
