Not better.

%usbconfig
ugen0.1: <OHCI root HUB AMD> at usbus0, cfg=0 md=HOST spd=FULL (12Mbps) pwr=ON
ugen1.1: <EHCI root HUB AMD> at usbus1, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=ON
ugen1.2: <FreeAgent Go Seagate> at usbus1, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=ON

HDD has only one cable connection, so it is powered from USB.

I made severals tests in a row, speed varies greatly stiil.
And there is no such problem with ICH7-based system (975XBX motherboard).
