Modified Files:
src/sys/dev/usb: ukbd.c
Log Message:
Fix WSKBD_RAW mode ukbd -> pckbd translation for Pause/Break and
Print Screen/Sys Req keys so xf86-input-keyboard can figure out
what we want.
Additionally, fix dead URL, and add a note that this emulation
is not completely identical to a real pckbd.
