Anyone successfully running Mythruna with an ATI Radeon X1900?

I have a buddy who is trying to run Mythruna but is seeing a link error in one of the shaders causing the application to crash.

I’m wondering if there are others able to run with this card or if there is something just currently broken. His driver is version 6.14.0010.6925 which he says his manufacturer says is the latest… but I’m not so sure.

For the curious, this was being discussed here: Issues running game

…though there really isn’t any more significant information there.
