One thing you might try is to exchange the order of arguments or do something similar. There are some comments by Nicolai on ordering of arguments in r300_reg.h, these might reflect actual hardware limitations.
For example, I do not understand why in flat texture shader one has to have two identical instructions and why the first and last instructions in
single texture shader are identical as well.
I couldn't find a combination that makes alpha look any better and got angry at the identical instructions which didn't do anything.
So I removed them.
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.
Hmm.. This is puzzling.
One more thing - try to compare console in quake (you can bring it up by pressing `) in game and end-game modes. On my computer it displays fine during the game (properly blended) but is "dithered" in end-game screen, even though I would expect quake to use the same code for displaying both.
