I'm not 100% sure, but I seem to recall thinking that they really
only did one column swap in the keyboard scan.  So, simply changing
which column-bit maps to which set of characters should do the trick.
Unfortunately, I'm not sure which columns are effected.  But, that
probably isn't too hard to figure-out if you just figure out which
characters are being read wrong...

Curtis, I think you will understand what I'm saying.  If not, I'll
try to elaborate... :-)
