No patch available. The 2.5 kernel has a complete rewrite of the keyboard handling, whatever the problem is has been fixed by the 2.5 kernel changes. Unless a keyboard expert on this list can point to patches that might reset the keyboard controller correctly after kdb has used polling mode then I am afraid that there is nothing that I can do.
