Got a 9250 as well with 10.1 CE.
So far I did not try to install the ATI because it looked quite difficult
even patches seemed to be needed in some cases.
Anyhow, I use fglrx that is shipped with 10.1 and during
the install I selected 9200, it all works OK
I am a newbee, so take this with a pinch of salt:
>install of fglrx_6_8_0-8.8.25-1 conflicts with file from package libxorg-x11-6.7.0-3mdk
does not look too good
you trying to put driver for 6.8 with xorg 6.7
When I googled looking at the radeon 9200 it seemed difficult
to mix and match versions (for a newbee anyhow)
If you manage please let us know. I am interested.
