Update: after some research I've determined natre of this color
distortion. It seems like card interpretes each RGB8 value (24 bits, 8
for each color component) as RBG4 (12 bits, 4 bits for each component,
red-blue-green order).

Thus, color which is 0xFF0000 (red) looks like magenta onscreen (red =
0xF, green = 0x0, blue = 0xF) and so on.

Doesn't anyone have any problems with nvidia driver on 6.2-RELEASE?

PS. Here's related thread on nvidia's forum:
