No.

Longer answer: this is a hardware limit (of all radeon chips up to
r480). Even for software mesa, I'm not sure you could increase it to a
larger value right now (precision issues?).
Beryl could probably break it up into multiple textures, though this
might have issues (texture filtering where the textures are joined?).
