Ok, I picked up some SATA hard drives now, and the AHCI driver DOES see them. However, it gets more interesting now.
The board has 4 SATA ports.
In the BIOS, all 4 of them work, and can start the bootloader from any of them.
In the kernel, ONLY the first two ports work.
The only thing I see on this, is that in my original dmesg, when the DVD drive was connected to the 4th port, and nothing connected on SATA1-3, SControl was 300 for 1/2 and 0 for 3/4.
