There's some chipset specific code necessary on i945 (which doesn't do
it completely correct at this time yet), so coreboot would be the right
place, not seabios.

This involves a couple of ATA roundtrips, but well, that's life. The ATA
code probably belongs in src/lib, for the benefit of all chipsets,
should they want to fully evaluate the ATA configuration.
