This is on a Geforce 3 TI. Have a look at this:
After installing Xorg 7 the 8774 driver wouldnt even start! The beta driver gives the color corruption in the image above. It seems like when writing the color value to a pixel the blue is written into the red bits somehow. 3D performance is really slow as well. Color is corrupted this way in all color depths (24, 16, and 8). My Xorg settings worked under 7xxx and have almost nothing in them (I tried various options to no avail).
