If the board has PATA ports driven off the chipset, then in AHCI mode

drive. Is that not happening on this board?
This is indeed the problem. In AHCI mode, the PATA port is undetected.
ata_piix does not handle it at all.

In compatible mode it's /dev/disk/by-path/pci-0000:00:1f.2-scsi-0:0:0:0
because i configured the bios to use PATA+SATA. This is the ICH7
controller (according to lspci).
In Enhanced AHCI mode it does not show up at all on lspci. Poking around
in /sys shows that ide-gd is responsible for discovering hda; without
CONFIG_IDE, it's not found at all.
The pata_marvell driver is unrelated, it only serves the two external
eSATA ports, nothing else. You can even see that it's situated close to
the eSATA ports whereas the Intel ICH7 SATA and PATA ports are on the
complete opposite side of the board:

Think you meant the sata_sil24 driver (it's a Silicon Image 3132 chip),
but yeah, it's unrelated.

Sure, compatible mode:

Enhanced ahci mode:
http://dx.infernix.net/ss4200/lspci-vv.enhanced_ahci_mode
From what I can gather from the ICH7 datasheet, when using AHCI the IDE
controller is supposed to show up as device 1f.1 and the SATA controller
as 1f.2. It seems like for some reason your BIOS is disabling the IDE
controller entirely in that mode, which appears rather wrong.
Do you have the latest BIOS for that board?
