They are present on some motherboards as secondary ata controller but are unsupported with tiger and leopard

So I did a try to insert pci id`s into AppleVIAATA.kext with known and usefull chipsets

• 0x611111ab - used at P5K-SE motherboard (Marvell 88se6111)
• 0x614511ab - used at Intel D975XBX2 and ASUS P5WDG2 WS Professional motherboard (Marvell 88se6145)

Installation

1. backup original AppleVIAATA.kext at /System/Library/Extensions
2. copy attached kext into /System/Library/Extensions
3. start Terminal and run: sudo chown -Rv root:wheel /System/Library/Extensions
4. remove /System/Library/Extensions.mkext and reboot

Post bugs here
