Well hell... Glancing at the code (at least at how it stands in 15.4), it
looks like it's dying in a pci_iomap... Or at the least, that's the only
relevant ENOMEM that isn't happening cause of a malloc failure. It looks
like the piix_disable_ahci code is pretty simple. I imagine enabling it
wouldn't be too rough either. Know offhand if Intel releases full
datasheets for these? (My guess is yes -- Intel is pretty good)?
