I just gave it a try. Like you described sio(4) doesn't work as console
regardless if it's the same port OFW uses or the other one. I just get
a "Fast Data Access MMU Miss" after "jumping to kernel...". However,
the first port works when flags are 0x0.
I still think the sio(4) files should stay gone in files.sparc64. Neither
sio(4) nor uart(4) are or were enabled by default in the sparc64 GENERIC
kernel. But uart(4) works as console for ISA devices and doesn't require
hints.
