Poor 5770 performance

[Badaboum03]

Hi guys.
I bought a HD5770 and I reinstalled my hack with Unibeast.
QE/CI worked OOB but benchmarks are poor.

Setting Framebuffer into com.chameleon.boot.plist?
AtiConfig=Vervet
AtiPorts=3 or 4 ,depends on how many ports has your card.

BUT, after sleep, it isn't as good as it was before :/
