Here's the low down by unwinder:

Mod your Radeon 9500 into a Radeon 9500 Pro or your 9700 into a 9800 with this patch. To excecute the script you'll need the latest RivaTuner 2.0 You must start it at least once, then simple extract and open attached file with Windows explorer, RivaTuner will do the rest. This script works with Catalyst 3.2 I planned to release RivaTuner 2.0 RC12.3 next Tuesday, but due to a _lot_ of received emails Catalyst 3.2 compatible SoftR9x00 scripts will be launched now. Fully featured RivaTuner 2.0 RC12.3 containing these scripts, updated SoftFireGL scipts for 1028 - 1030 drivers and other new features for ATI and nVidia boards will be launched on Tuesday as supposed. Besides Catalyst 3.2 support, the scipts allow you to force RADEON 9800PRO PCI DeviceID and force the driver to detect any R9500(PRO)/9700(PRO) as R9800PRO.

I added this mode special to check R300->R350 info posted by www.tommti-systems.de. I must note that after this mod the driver uses R9800 specific code for sure and the control panel displays Smoothvision v2.1, but I didn't managed any boost comparing to R9700 mode. Don't spam me with question about that, address your questions to www.tommti-systems.de.

I'm afraid that their "R350 = R300 + optimized drivers" formula is incorrect.
