apparent key mapping error for usb keyboard

[Michael Tokarev <mjt@tls.msk.ru>]

I've a debian bugreport that claims to have a fix
for apparently wrong keymap for usb keyboard.  I
noticed this before with ps/2 keyboard too, the
sympthoms were that e.g windows keys were not
working in guests, but later on that has been
fixed.  But with `-usbdevice keyboard', i.e. with
usb keyboard, it still does not work.  See
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=578846
for details and for the proposed patch which
fixes the mentioned issue.  Here's the patch itself:

I'm not sure if it's right fix however.  Hence I'm
asking for opinions here.  If it's a right way to go,
it should probably be applied to -stable too.

Thanks!
