Re: [ES40-developers] 8042 translation is faulty

Nope, that didn't seem to do it.  Here's the debugging output of me
hitting 'b' on the keyboard in SRM (where it works) and netbsd debug
(where it doesn't)

--- in srm --

gen_scancode(): writing raw 32

READ(60) = 32   
service_keyboard(): no keys waiting   
gen_scancode(): 21 released  
keyboard: gen_scancode with scancode_translate cleared   
gen_scancode(): writing raw f0
