Looks like this huge delay is caused by the inb() being astonishingly 
slow, which is not factored by the timeout routines. Reading keyboard 
status port once takes about 0.003s! I am not sure if it's common 
behaviour of the platform, or something specific to this particular 
model. Do you know by any chance?
