"console=8250" probably would have been a better choice. I think this could be changed without too much hassle. It might be possible to extend "console=uart" so one could do "console=uart,io,0x3f8,9600n8,21285" (where "21285" is a non-8250 UART type). But that seems ugly to me. I'd rather have "console=21285", "console=68328", etc. I just want the "console=<tag>" to explicitly identify the UART type so we don't have to poke at the thing and guess what it is.
