Switching controller mode in software?

Hello everybody,

I have a notebook with the Intel ICH7 chipset (see attached lspci
output). Unfortunately, the SATA controller is stuck in non-AHCI mode
and the braindead bios doesn't allow me to change that. Is it possible
to change the controller to AHCI mode in software, e.g. through ACPI?

Thanks, Yours, Florian
