No issues with this one:-

00:1f.2 SATA controller [0106]: Intel Corporation 82801HBM/HEM (ICH8M/ICH8M-E)
SATA AHCI Controller [8086:2829] (rev 03) (prog-if 01 [AHCI 1.0]) with a
WDC_WD5000BEVT-80A0RT0 disk.

However, the controller appears as a SATA-IDE controller (8086:2828) that uses
the piix driver by default, and you need a custom kernel (AFAICT) to quirk the
8086:2828 controller into AHCI mode whereby it turns into 8086:2829, and uses
the ahci driver, allowing for the SATA link power management.
