I am not quite sure what you're looking for. 32bit RGBA textures are certainly not a problem (neither are 16bit RGBA), pretty much only a maximum of 8bit is supported per channel (though the chip could in theory support a 16+16 format too). If you feed the driver formats it doesn't understand it should still work but the data will get converted (see r200_texstate.c to easily see what format your data will end up).
