syscons support for ia64

[Rink Springer]

Hi all,

I've finally managed to get to my syscons ia64 vga-driver up-to-date.
It implements a vga(4)-like driver which will actually work on ia64
systems (in fact, I'm pretty sure it would work on i386/amd64 too but I
have not yet tested this theory)

The patch is available at:

http://people.freebsd.org/~rink/ia64/ia64-syscons-20100207.diff

Note that a rather serious caveat is that it just assumes you have a
VGA-device, it will not attempt to detect it. My goal is to just look at
the memory map to see if the appropriate ranges are mapped to I/O and if
this is the case, assume VGA exists.

Anyway, it'd be nice if someone could test this. I plan on committing it
once I finish up the detection support so it can be in GENERIC.

Regards,

Works great. There's just 1 minor point:

The console is determined by the HCDP information and uart(4)
respects that. syscons doesn't and it simply claims the console
even if the HCDP information says the console is serial. With
syscons I need to boot with -h to get the serial console.

It would be great to have syscons respect the HCDP information
as well so that one can select the console in EFI and see that
FreeBSD automatically adjusts.

FYI,
