ATI 9600 XT and WindLight in Linux

I would like to share one of my results from all my testings:

I got my ATI Radeon 9600XT working with all efects in Linux WindLight 1_18_6_76886. Less than 10 FPS with everything ON (Ultra High), and more than 30 FPS with Low graphics setting.
That was possible only with the latest WindLight Viewer and ATI proprietary fglrx driver 8.40.4.
I had to disable the black listings for ATI in featuretable_linux.txt and set Class3 for the ATI Radeon 9600 in gpu_table.txt.

Here is a summary of my conclusions (in Portuguese):

PS: Works only in Window mode. Fullscreen mode crashes the viewer.
