I doubt 3DMark2001 uses all 6 texture units even in the high shader test
because it works on Nvidia cards which only support 4 simultaneous textures.
If it uses 4 textures and 6 or more texture stages(ie, texture stage settings
that do not sample from a texture), it might be worth looking into the
texture map stuff we're using with the nvidia register combiner code. With
atifs we can support 6 simultaneous textures and 8 texture stages.
