Surprisingly I couldn't collect uart information yet, I just=20 found out that I can't use uart for serial console (on i386), at least not= =20 if all I do is to replace sio with uart in my kernel config. Since I don't understand the code I have no idea why I would want to use=20 uart. Is it beneficial (on the i386 arch) to have a newbusified driver?
