You have to use closed source ATi drivers if you want it to work on Wine with heavy games like HL2.

I'm write, that I use that driver. Because it's any one who support 3d acceleration for R500 or more chips.
Drivers: x11-drivers/ati-drivers-8.476 ( ati-driver-installer-8-4-x86.x86_64.run )
I's the fresh driver.
