ATI doesn't have any proprietary extensions for exposing the R300 shader functionality, only "ARB2" (ARB_vertex_program and ARB_fragment_program) so there's no way to do "specific" R300 path.
The leaked alpha does support ATI's two-sided stencil extension (ATI_separate_stencil) which is only implemented on R300.
They have at least hired Mark Vojkovich, a principal XFree developer, who has made or worked on XAA (the acceleration part of X), Xinerama (multihead), DGA (direct graphics access), Xv (video extension) and most of the drivers. So he alone is very valuable addition to the team.
