generate a C file containing the selected mode timing parameters.
Read the comments at the start of the file for details on use.

49c62c4336 Changes to support fork_kthread(): 
- cpu_set_kpc() now takes void *arg third argument, passed to the

- cpu_fork() allows parent to be non-curproc iff parent is proc0.
  When forking non-curproc, assume its state has already been saved.

During the early bootstrapping use fcomcnattach()/fcomcndetach to enable
debug and diagnostic information to be sent to the diagnostic serial

have been relocated and the real console can be initialised().

18ccba3b4e Make sure ISA interrupts have been setup prior to configuring devices. 
This is not nice and a better solution is needed. Really this should be
done when the PCI-ISA bridge is discovered but it is possible that
some PCI interrupts may be routed via the ISA interrupt controller
and thus this needs setting up first.
