I recently had the need to update the display driver of my old Toshiba Satellite M50 laptop. The onboard videocard is an ATI Mobility Radeon X600 SE. When trying to install the legacy Catalyst drivers, I got a "chip not supported" error, and a hint telling me I should check on the Toshiba website.
Unfortunately, the driver on the Toshiba website is 4 years old, and doesn't support 16/9 resolutions which is what I was looking for.
It comes out that the Catalyst drivers can actually be installed on the Toshiba, but it needs a bit of hacking. First, I downloaded and installed the Mobility Modder . Then, I took the latest legacy Catalyst drivers on the ATI/AMD website.
I used the Mobility Modder to alter the Catalyst intallation package and then, bingo, I could finally update the display driver with an up to date version.

Same trick can work under Windows 7.
