Misrenderd stars from Celestia

All the stars in Celestia are rendered as yellow dots(zooming in on one gives something that looks correct, however); r600g gets the colors right(if not the shape, but that's another bug), so this seems to be a driver issue. I've tested it on a Radeon HD 3450 and the bug was originally reported on #radeon today by djzn, who tested with an HD 3200 and HD 2600XT and got the same result. Celestia mentions loading a number of ARB shaders, but with no error and gives no indication of problems(output below).

I can confirm this on Radeon HD 4350, using R600c, Mesa 7.10.2, kernel 2.6.38.4, KMS - stars are all yellow. Using software rendering, the stars are different colours - that is probably the correct rendering.

On R600g, Mesa 8.0rc2 the stars seem to have proper colors.
