As a recap, I figured out that my lack of acceleration was caused by having the "-ass" flag in my mplayer config - without this flag (for better subtitle support), vaapi appears to fully accelerate.
mplayer-vaapi-20091228 (and earlier snapshots) simply don't render ASS subtitles in vaapi mode; I suppose January's builds are better in that respect.
I found a good sample clip to demonstrate ASS subtitles here: http://matroska.free.fr/samples/mewmew/
The "mewmew-vorbis-ssa.mkv" clip has 15 different tracks of ASS-format subtitles. Using mplayer-vaapi-20100105 or mplayer-vaapi-20100114 with "-va vaapi -vo vaapi:gl -ass" options, you can see the colorspace/-vf scale warnings in MPlayer:

Code:
mkvmerge -o birds_subbed.mkv Bird_42_MBit_ABR_\(+-1.5\ MBit\).mkv -D -A --default-track 5 mewmew-vorbis-ssa.mkv
- I include the -ass option, which causes mplayer to render the subs properly (as in the matroska site's screenshot), but without hardware acceleration
- I omit the -ass option, which enables hardware acceleration but causes the subtitles to render improperly (all white lettering and misaligned text)
I now see that I forgot to answer some of gbeauche's ques4tions

- The output of running "~/mplayer-vaapi-20100114/mplayer-vaapi/mplayer -vo vaapi:gl -va vaapi -msglevel decvideo=9:vo=9 -ass birds_subbed.mkv" can be found at http://pastebin.com/f1c47c28 (132KB of logs..). birds_subbed.mkv is the high bitrate subtitled version of Birds_42, created using mkvmerge as described earlier in my post.
- mplayer-vaapi-122809 with xvba-video-0.6.2 is able to accelerate all of my videos when using the -ass option, but unfortunately it skips subtitle rendering in this case. So far, no version of mplayer-vaapi has played a video with ASS subtitles correctly for me.
