Hi,
this is a patch which at least gives me some bootup messages on the prom
console ...

The naming scheme for the "prom console" as a serial device ("ttySN") isnt
that good afaik as the setup for the serial console and prom console
could get mixed up - right ?

I dont think calling "sgi_prom_console_init" from arch_setup is correct
but where should this be placed better ?
