Mix map materials no longer exported properly

If you create a mix map with two bitmap textures to combine it only exports one 
of the textures.
This happens for Max 2011. For the old version of the plugin for Max 8 this 
worked fine.
So, basically, now there is no way to export light mapping.

How to reproduce:
Select a new material, click on the map button for diffuse. For the material 
type choose "Mix". For colour #1 select a bitmap texture, for Mix Amount, 
select the light map texture. 
When you export only the light map texture is exported, the other texture is 
ignored. 
This is what is exported:

This is what should be exported (i.e produced by old exporter for Max 8):
