> Has anyone got any idea why the alpha channel isn't being correctly written
with fragment programs, and why I get blue patches after the commit I mentioned
earlier?  I'm not sure about the first, but the later could be the texture
format is incorrectly selected? As far as I can tell, that's all the commit
does; selects a different texture format based on a few things...  I really like
to see these bugs fixed, but there hasn't been any real activity on this bug for
a while now. :( 
There is almost no such thing as incorrect selection of the internal texture
format - the driver is really free to choose almost whatever it wants. The patch
really just tries to select a format which will result in a memcopy from the
user-supplied format instead of requiring conversion (since the r300 chip can
handle the necessary swizzling on its own later).
Could you try with a r300Choose8888TexFormat function which always returns
&_mesa_texformat_rgba8888, ...rgba8888_rev, ...argb8888 and ...argb8888_rev
respectively? btw does your app always use the src format of GL_RGBA and the src
type GL_UNSIGNED_BYTE (like almost everyone does)?
