Hello,

I think I know what's wrong - our PS/2 keyboard driver identifies itself as an XT keyboard but in event mode ( reading from /dev/wskbd* ) it translates AT extended scancodes ( that's more or less every key that's present on an AT keyboard but not an XT one ) to not-really-standard single byte codes which the kbd driver in X ignores because it expects XT codes and maybe AT multibyte codes. So what I need to do is to add another translation table to said driver to deal with those codes. Hopefully that will make those keys
work. Doing the same thing for Xorg will be trivial.
Talk about an ancient bug.

... 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
