Hello Arnaud
From my understanding, there's no support for this device because it
seems to have an issue
handling more than 1 drive without locking up and destroying the filesystem.
Correct me if I'm wrong guys .. I've tried on several occations,
first time the ahci system failed completely, next time it worked with
the x86 build, but not on the x64
build if the system had more than 4Gb ram.
Current kernel builds work out pretty stable, untill you plug 2
drives. Concurrent writes will lock
up the controller and bye bye filesystem.
I'm not enough of a kernelhacker to figure out the root cause, so all
I've been able to do is test.

Have you tested a recent kernel with this device? It looks like it
should have the proper class code so the AHCI driver can load without
that specific device ID. Adding specific device IDs should only be
needed for devices that don't do this (like those that identify as RAID
or legacy IDE classes).
