I bet these are "legacy free" machines, right?  I recently noticed 
that recent Intel chipsets cause incredibly long delays when 
non-existent ISA ports are accessed, most notably AT keyboard ports.  
(My gut tells me it is going in and out of SMM repeatedly for 
nothing.)  Back in the old days, when we had real ISA bus, it used to 
delay very short and fixed amount time.  Those days, this behaviour 
was even (ab)used as a delay function where a real timer is not 
available yet. ;-)

Try getting rid of all unnecessary device drivers from your kernel 
configuration.
