ok, i think i need some advice on this.
the problem: on bootup, console_setup and write_console get called rather 
early, kmem is not initialised and so kmalloc and irqs don't work, so
i can't use open_chan_pair.

the thing is that write_console uses raw() and cooked(), so when the tty state
finally gets to me, through con_open and open_chan_pair, it's already been
messed with.

i was thinking about adding one more parameter to open_chan{_pair} which
would allow setting up irq without actually calling the open_{fd,tty} funcs.
so console_setup calls open_chan_pair, which only opens the channel but
doesn't setup the irq and later con_open calls open_chan_pair and sets up the 
irq.
but again, the memory allocation problem remains: alloc_bootmem doesn't sound
like the right thing to call, kmalloc doesn't work at that stage in boot up and
the only thing left is malloc.
