Keyboard not working in 5.4

[Matthew Dillon]

I have pushed a commit to master and release which disables the FADT probe
(it can be turned on again with a tunable).  I just changed the global from
1 to 0.  Please re-test with the latest DragonFly_RELEASE_5_4 sources and
tell us if that fixed the issue.
