After doing exactly what was suggested here I can say that finally ATI
drivers work for me and I can switch between cards.
And finally with latest drivers I can use switcheroo to switch to one or
other card.

But unfortunately even with fglrx some things do not work (gnome-shell
task bar colours turn psychedelic :)

And I can't get hardware accelerated WebGL at all no matter what
configuration.
In fact on my computer (ATI 5470 + Intel i5) WebGL only works with
software rendering and if run like that it is fastest with open-source
Intel card on.

So test is:
Open Chromium browser and Start
http://webglsamples.googlecode.com/hg/aquarium/aquarium.html
click Change view to see external view (out of the aquarium)
click Options and enable everything

So with Ubuntu 11.04 open-source radeon drivers: (echo DDIS >
/sys/...../switch  and logoout -> login)
4 FPS

With Ubuntu 11.04 open-source intel driver (  echo DIGD >
/sys/...../switch  and logoout -> login)
22 FPS

WIth FGLRX installed 
less htan 1 FPS

If I try with Firefox and disable mesa and software rendering of webgl,
it does not work at all.

Also I have some basic OpenGL examples that use GLUT and basic graphics
- blending, stencils and fog, they run much slower with radeon open
source than with intel opensource, and speed with fglrx is similar to intel
