Does this texture have an alpha compent?  If so, then consider that
OpenGL chops this into 4-4-4-4, so you are only getting 4 bits per
color channel on a Voodoo card.  Clouds also have this problem where
they look much nicer in gimp, but band like crazy inside flightgear.

Yet another reason to upgrade ... :-)
