I saw something somewhere about AHCI support requiring kernel 2.6.19 or later. But the current CentOS/RHEL stable kernels are 2.6.18
I'm trying to run CentOS/RHEL in a VirtualBox vm, which by default creates sata virtual disks with an AHCI virtual controller.
These virtual machines are quite unstable, and I'm wondering if the AHCI virtual controller is the problem.
I do have a real physical AHCI controller and I'm wondering if I should try it on a CentOS/RHEL 5.5 box, or if I should wait for RHEL/CentOS 6, before even attempting it.

RHEL/CentOS 2.6.18 kernel is very far from kernel.org/upstream 2.6.18. RHEL/CentOS 2.6.18 kernel contains a LOT of bugfixes and also feature-backports from newer kernel versions.
.. including AHCI drivers.

Drivers, etc. are back ported.

I have a nVidia AHCI SATA controller on my system:
00:09.0 SATA controller: nVidia Corporation MCP78S [GeForce 8200] AHCI Controller (rev a2)
And it works fine with CentOS 5. (It even works fine under CentOS 4.8!). I did have to add the 'irqpoll' kernel parameter.
