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 ;-)
