I installed CentOS on a 1U server with a SI SATA Controller

According to lspci a
CMD Technology Inc Silicon Image SiI 3112 SATARaid Controller (#2) (rev 2)

The problem is for some reason the system came up without DMA. Of course 
this means terrible IO performance. Aside from setting it with hdparm is 
there a way to have it do this on boot? Is this a known issue?
