I just bought a new motherboard, Asus M3A79-T.  The hard drives I am

/sys/block/sda/device/queue_depth It gave me a 5MBs boost but that was 
all.  I also tried blacklisting ata_generic but that didn't help 
either.  I am kind of out of ideas on how to trouble shoot farther.  
Any one got a clue?

You left out the most important bits of data:
What kernel are you running?
Stock or home-rolled?
My bet is that your kernel doesn't have the proper chipset module 
compiled in it.
