... and that's exactly what happened. Here
ftp://ftp.netbsd.org/pub/NetBSD/misc/macallan/shark/bsd_KeyMap.diff
is a patch that should make the kbd driver work properly with PS/2  
keyboards, you'll need an InputDevice section like this:

Section "InputDevice"
    Identifier  "Keyboard1"
    Driver      "kbd"
    Option "AutoRepeat" "500 30"
    Option "XkbRules" "xfree86"
    Option "XkbModel" "pc101"
    Option "XkbLayout"        "gb"
        Option "Protocol" "wskbd"
        Option "Device" "/dev/wskbd0"
EndSection

XkbLayout and XkbModel may vary of course.
Without the patch the cursor keys and a few others won't send any  
events, with the patch they should Just Work(tm).
Since this isn't really shark specific followups should go to tech-x11.

Yes Joerg, I'll adapt it to Xorg and request pullup to 4.0 as soon as  
I get some feedback.

have fun
Michael
