xkb problems with usb kvm

[Alex Deucher]

I have a usb kvm that doesn't work properly with xkb.  it used to work
fine with xorg 6.7 and the "keyboard" driver.  it also works fine in
the console.  When in X however, the alphanumeric keys work properly,
but all the other keys (arrows, insert, delete, etc.) seem to produce
the wrong event (they all seem to cause the screenshot tool to come up
in gnome; not sure which keycode that is off hand).  Unfortunately I'm
not at all familiar with xkb.  could someone point me in the right
direction?  Is this a configuration problem or a hardware problem?

Thanks,

Alex
