I've tested the patch and it definately better, as in less frames are
dropped/skipped. The fps indicated by xbmc is now 23.98fps as expected, but
every so many seconds it drops to 22fps. Without the patch it was 23.95fps and
dropped to 22fps so many seconds.

The PLL values are now:
23.976 content: [drm:radeon_compute_pll_avivo], 7416, pll dividers - fb: 17.8
ref: 2, post 12
50fps content: [drm:radeon_compute_pll_avivo], 14833, pll dividers - fb: 17.8
ref: 2, post 6

So compared to without the patch it is closer to the perfect value, but still
not there. So since the frame rate is closer now I expect the only way to get
it to work properly is to get a perfect match I guess.
