I have seen this problem before on a Dell P75 and a P100 where the keyboard and
mouse are PS/2 styles. Usually, unplugging the mouse and/or generating keyboard
and mouse interrupts during the bootup would let you slide past the problem.

I think (I have not investigated this sufficiently to be sure) that it
has something to do with how FreeBSD is reseting this particular set of
kerboard/mouse controllers. 

This message is to act more of a confirmation that this isn't one particular
machine, but a group of them. 

I have, however, had the boot disk work on other Dells of the same type. The
only thing that made this one different was that the flash ROM code for
the machine had been upgraded to the "latest" release for that particular
machine (I wasn't the one who was responsible for doing it, so details
are second hand). Perhaps this ROM change was sufficient to cause
the problem (probably was), rather than it being a change in the FreeBSD
console driver.
