It should work. My complete guess is that the module is too large.
Maybe try building it into your kernel? I suspect that might make the
problem more obvious.

I don't expect the 2D driver will work without the kernel module.
Focus on the kernel module first.

I've had a Radeon 9100 working in an alpha, as well as others. A 9250
should work.
