I'm having trouble finding time to play with wine & games recently, and
also I haven't bothered with fglrx for over a year, but I can tell you
that if you want to use the open-source drivers, you should closely
track the latest driver developments. I would personally build
xf86-video-ati and mesa from the latest git sources. Alternatively you
can try to find someone's binary packages if they update them recently.
In particular, there is some discussion in the mesa list:

So you'd want to watch for when this lands.

I can't help you with uninstalling Ubuntu's ATI drivers and building
your own. I use Gentoo and I don't want to help you break your Ubuntu.

As for performance, there are some options that you can set with driconf
that can improve performance, but you'll have to search around somewhat
to find exactly what option for what app. You can also use sysprof to
profile your system and hassle wine / mesa devs with pretty output
graphs :) This approach actually did wonders for me with an integrated
Intel video chip on my old PC - Intel devs did a simple patch that
doubled 2D performance. Cool.

Lastly, if you try to run Cedega or Crossover ( but not native wine ),
keep in mind that you'll need 32-bit binaries of your drivers, otherwise
you'll get software rendering. fglrx includes 32-bit binaries, but I
haven't yet figured out how to build 32-bit binaries on my
( non-multilib ) 64-bit Gentoo system.
