Snapshot of the artifacts with normal map

Light blue garbled artifacts are affecting gallium nouveau on FreeSpace2 open
source, with Star Wars : Original Trilogy mod.

To Star Wars fans this may be unacceptable :-), so let't try to find clues to
the problem

I have checked the .dds normal map's texture compression format and in this mod
it's always DXT5

If I disable 'normal maps' in wxLauncher there are no artifacts, but there are
also no maps, which are one the beauties of the mod.

Affected chipsets NV6x (GeForce 7025) NV8x (GeForce 8500, 8600), NV9x (GeForce
9600GT, GT120) , NVAx (GeForce 210) and NVDx (GeForce GT610). (cheched mesa
with 10.6.x)

Unaffected, meaning normal maps are fine with those: NVCx and NVEx chipsets
(checked with mesa 10.6.x and 11.0.0devel git)

NOTE: It's strange that NVDx chipsets are affected, if they rely on nvc0 driver

You can find in the attachment the snapshot of the artifacts with normal maps
and  normal maps disabled (no artifacts), plus other log files/extracts.
