You'll also need to update all the config scripts and Makefile bits. Even
if you do that however 2.6.18 and 2.6.28 are somewhat different -
sufficiently different it wouldn't build or work.

There is a backport of the later ATA code for kernels of that sort of era
in RHEL and thus Centos that might be more helpful to you, but its a
backport of the entire layer rather than just odd driver bits.

Assuming you don't need any of the latest and greatest features however
the 2.6.18 ahci driver *ought* to drive the ICH10 SATA controller just
fine if you add the idents from 2.6.28 (or the class match for AHCI) to
it
