So what are you gonna do on my box when I install a PCI USB adapter? Then I
can have PS/2, ADB and USB keyboards.
If you use XF68_FBDev with XKB disabled, it will ask the kernel for the mapping
keycode/keysym, and it'll work automagically with whatever type of keyboard you
have. So user space programs do not have to know about a specific keycode
mapping.
