Turns out that the 2nd problem I discribed is the whole issue. The red, green 
and blue colors come from the emissive material property(which tracks the 
primary color), while the alpha channel comes from the diffuse property(which 
also tracks the primary color). In opengl only emissive OR diffuse can be set 
up to track the vertex color. So we either get the correct color, or the 
correct alpha, but never both.

A solution would be a replacement shader, or drawing the vertices in immediate 
mode and change glMaterial every vertex. The glMaterial man page says its 
legal, but will be slow.

The funny thing is that the parameters eve sets up have exactly the same 
result as disabling lighting. It would be possible to catch this condition, 
but it would link many states together and result in a huge if statement that 
addresses a very specific bug in eve.
