I had a problem starting XBMC on Windows 7 on my old Shuttle destkop with an ATI Radeon 9600 XT graphics card and the default W7 graphics driver – ATI discontinued support for a bunch of old graphic chips including mine, I went and on ATI website for a driver for Windows 7 and Radeon 9600 is not in the list anymore.
Luckily MerlinUK posted on ATI forums how to install the ATI Catalyst 9.3 legacy drivers for Windows Vista on Windows 7 and it works, XBMC running fine now, see below.

I have been trying to find a way of installing Catalyst 9.3 in Windows 7 to support my X700 AGP card. After a bit of trial and error, I have found a way that this can be done. This not only installs the 9.3 drivers but also allows use of Catalyst control center. This method should work for all legacy cards supported by catalyst 9.3.
There are five Step to the installation although step five is optional.
Step 1: Start the installation as normal upto main installation then cancel. This will extract the driver files to your hard drive.
Step 2: navigate to C:\ATI\Support\9_3_vista32_win7_32_dd_ccc_wdm_enu\pakages\drivers\display\LH_INF. Open in notepad CL_76828.inf and look for the following entry;
%ATI% = ATI.Mfg, NTx86.6.0, NTx86.6.1
edit it to read
%ATI% = ATI.Mfg, NTx86.6.0
Step 3: manually install the display driver by clicking on start and entering Device Manager in the search box select your graphics adaptor and update driver select the second option and have disk browse to the inf file you saved in Step 2. Windows will display a warning but click yes
Step 4: Navigate to; C:\ATI\Support\9_3_vista32_win7_32_dd_ccc_wdm_enu and run setup this will install the Catalyst control center without error. reboot and hey presto
Step 5: Not strictly needed but will save you having to do the above again if you have to re-install Windows 7, save the ATI folder to a USB drive or CD. Just follow steps 3 & 4 in any order.
And that is it, hope this helps...
