OK, it seems that the kernel I have (stock CentOS 4.7: 2.6.9-78.0.22.EL i686) seems to gronk the nVideo SATA controller in AHCI mode. It is NOT able to deal with the SATA DVD Burner I have. It is a "Sony Optiarc DVD Burner with LightScribe Black SATA Model AD-7241S-0B LightScribe Support". Is there some special magic I need to do? Here is the relevant bit from the boot up (SATA ports 2-6 are empty at present):

You could try booting with the boot command line option:
pci=nomsi
and see if that helps

No effect. Same 'Failed to IDENTIFY' messages.

I just tried adding 'irqpoll' and this seems to have cured things -- the DVD Burner is detected! I'm guessing it is a case of broken firmware somewhere (which seems to be the purpose of the irqpoll parameter).
