Hmm. The "Legacy Stuff" in most chipsets is left out. And is usually
put on the ISA bus, or on the LPC bus (Software wise it's ISA but the
hardware is noticeabley different). The third party superio chips
aren't expensive and can handle all of that stuff quite simply.
Legacy free boards are calling the port to plug in a UART an Debug
Port. But I haven't seen serious suggestions to remove them from the
architecture.
Ollie I don't quite see what you are saying no to.
