[parisc-linux] Start sash ...

Ok, after hacking half of the night and cursing about a totally fucked
up ffz(), I finally got something (see below). I did some dirty hacks
to get it so far. 

There is something wrong with user page mappings. It looks like brk()
memory is read only mapped. After digging a little bit, I decided to 
workaround this, by mapping every page read/write/execute (dirty hack #1).

The serial port doesn't seem to generate interrupts. So I had to hack the
serial output routine by printing via printk (dirty hack #2):

And sash really doesn't like garbage in argv[], so I cleaned argv before
execve of sash alias init (not so dirty hack #3).

I'll dig into the serial interrupt problem later, since this holds me
back from being setup up for Systems.

Thomas.

   This device has completely bogus header. Compaq scores again :-|
It's a host bridge, but it should be called ghost bridge instead ;^)
