I don't se any problem without these innstuctions. unless there are special cases. q3a and NeHe lessons 2-20 don't look any worse.

I haven't looked at the r300 code as it's not in Mesa CVS, but I'm wondering if you've noticed that the i915 driver does a similar task of converting fixed function GL to a programable fragment shader backend?
