SubjectWho can backport the AHCI driver to older kernels

I need help and/or advice on the following problem:

New mainboard platfrom with latest chipset from a chipset vendor that
can't do the job that we are asking for. The chipset (especially the
SATA controller is supported in Kernel 2.6.24 and later.

The target market for those boards is using old fashioned distributions
like CentOS, Debian, Fedora 8 openSUSE 10 and so on. So the gap is that
the latest driver from 2.6.24 is not yet in those distributions. The
impact of this is that the customer in the target market can't use the
mainboards to run actual Linux distributions on them.

So there is a need ot backport e.g. the AHCI driver from 2.6.24 to
2.6.16 or 2.6.18. Doing a diff on the sources makes me think this is a
sort of "mission impossible" since it sureley isn't just the ahci code
that changed but also a lot in the kernel infrastructure meanwhile.

So what options do we have to help the customer? Changing to 2.6.24
kernel is not an option due to the customer. So it looks like the
only way to "solve" this is a backport, but then we come to "who can
do this?".

Any hints welcome and thanks a lot for your attention
