It never froze on me, but try selecting the US keyboard and then edit your XF86Config-4 file. You can try mine from here: http://kargellan.ucc.ie/~mulcahyb/public/resources/sparc/linux/setup/XF86Config-4 I then tweaked the Xmodmap to get the symbols exactly right for @ | etc. again you can get mine from here: http://kargellan.ucc.ie/~mulcahyb/public/resources/sparc/linux/setup/Xmodmap Hope this helps.
