This is not 64bit space, but a ranges going backwards. Not keyboard related.

Now that one is really really bad. You could try to make sure port
0x60,0x64 irq 1 are used as default ports in probing.

And that's the missing PM timer.
/proc/interrups /proc/ioports /proc/iomem
would also be useful to compare.
