Let me try and do this right.
Here's the bug report:

ICH7 SATA drive not detected.

I have two new OEM machines that are both ICH7 chipsets. Both
machines give the same vendor and device PCI ids for their storage
controllers. 8086:27df and 8086:27c0. One of the machines' disks is
being detected correctly (sda). The other one is not. I have tried
modprobing both ata_piix and ahci with negative results. It is very
new hardware. There is also a broadcom NIC that is not being
detected, but I don't NEED that to work. (I'll file a bug if requested
of me.)

keywords: piix, ICH7, SATA, ata_piix, ahci

I'm running 2.6.11-rc5 in a custom distribution in a ram disk from a
pxe boot. I also have a USB memory device inserted into the machine
being detected as sda for the reports below.

Here's the output of ver_linux:
