I thought the r300 driver could already handle tcl fallbacks. It's not news that the xpress chips don't have any hw tcl/vertex shaders, that has been known forever and is afaik officially confirmed (the screen code doesn't set the RADEON_CHIPSET_TCL bit for these chips for a reason). The same is still true for rs690, btw.
