[parisc-linux] 712 STI support

[Steve Shack]

Hi,
    Earlier today I was looking at the Openbsd hppa porting page. I
noticed they appear to have support for the STI. I've downloaded the
source and looked at it and it seems that yes. They have some support
for the sti there. So this weeks project for me is getting that going.
They also have floppy/audio going. But STI's a higher priority in my
opinion. If anyone has any problems with this let me know.
