I wish I had an answer for you, because I'm having the same issue
with a GX280 running Windows XP SP2 and a USB keyboard. Sometimes at
restart we get absolutely no keyboard function at all. I tried swapping
the ports that the mouse and keyboard were plugged into - and that
seemed to fix the issue, but it came right back the next day. I tried
rolling back to SP1 and even no SP - but the issue followed, so I'm
pretty sure it's not a SP issue (at least in my case).

I really wish I had stumbled across before we
purchased all our new computers this year, I would have had a bit more
warning about all the issues Dell was going to give me.
