Instead of having this should we just add the GT-I9300 and SCH-I535 to the vp8
blacklist? It kind of unnerves me that a single bit has so much impact on the
viability of these devices.

i don't think that the s3 has hw vp8, just 264.  caleb showed me that it's
running fine in the lab for 264 now with adaptive disabled.

maybe i should remove the mime check..?
