I'm not sure if this is your problem, but there is a line in generic:
device		ukbd		# Keyboard
toward the end, under #USB Support. Have you already tried commenting that 

As a side note, the above PS/2 keyboard config. (yours) matches what I have 
in my kernel. (with the flag.)

Good luck,

PS. re-installing is overkill here; the answer must be simpler. Though it 
may be quicker in the long run.
