Ahh, right.  But now we're talking about keyboards, when before we were
talking strictly about mice.  Then I remembered that the PS/2 interface
actually handles both keyboards *and* mice during initialisation, which
means the translation/emulation layer does the same thing.

The problem in that thread is partially documented in the ukbd(4) man
page; see the paragraph starting with "If you want to use a USB keyboard
as your default".

The "hint" commands shown should do the right thing.  However, *do not*
add them to device.hints -- add them to /boot/loader.conf.  device.hints
can be overwritten when changes occur in it (I forget if installkernel
or mergemaster does this), and you will lose your changes.

You can also type the "hint" commands into the loader section prior to
booting.  The OP might want to try doing this: at the FreeBSD
Beastie/loader menu, hit 6 to go to the Loader prompt.  At the prompt,
type in:

set hint.atkbd.0.disable="1"
set hint.atkbdc.0.disable="1"

And then tell us if your keyboard works during sysinstall.
