There are workarounds in the driver for this (see r200UpdateTextureState), but to my knowledge they are insufficient for two-pass ATI_fragment_shader shaders. There's also a mesa test which last I heard showed errors (progs/tests/afsmultiarb) (you can switch the test between one and two pass shaders). If this is the problem, you could try running doom3 using the arb path I think something like doom3 +seta r_renderer arb might work, however arb path looks ugly (r_renderer defaults to "best" which will then choose "r200" on this card). Unfortunately I don't know how this could be fixed, as documentation for these asic bugs is nonexistent (or at least non-public).
