Seems like not. Even if this chip supports AHCI (only if it is ICH7R or
ICH7M), BIOS haven't enabled AHCI mode on it. If it would do, you would
see subclass = SATA and one more memory bar here.

 .. and it seems that PCIR_BAR(5) is already set as I/O, you could try
adding the INTEL_AHCI attribute to the entry for ATA_I82801GB_S1,
which matches your chip-id and see what happens.

I have not tried this - please make sure you have a full backup first!

PCIR_BAR(5) is not set in this case, only 0-4. It won't help.

Ugh! My bad .. the only other option is to adjust the entry in ahci.c
for that chip-id, find a suitably free memory window and do something
like the attached patch (set 'AHCI_MEM_HACK' to the base of whatever
window you can allocate).

I use this on a Toshiba A-105 laptop but, in the process, I lose the
ability to talk to the PATA DVD-drive (the reason why the manufacturer
set compatibility mode in the BIOS).

On the other hand it gets me the (huge!) benefits of NCQ ;-)
