Leopard Keyboard Freeze Workaround

Sometimes my keyboard freezes in in leopard apparently this is a known issue. You can fix it if you plug-in a usb keyboard! At least it worked with some dell keyboard that was floating around my desk. That would be a fun bug to track down. It triggers rarely and seems to be related to spaces usage. I thought about submitting the bug to apple but I couldn't find their bug tracker! I guess big companies don't need or care about user submitted bugs.
