There is ahci(4) manual page in 8.0-PRERELEASE but no ada(4) that is linked here. I've just tried "Modular ATA" configuration of Intel ICH7-based system plus "device ahci" minus all traditional ata(4) kernel configuration, the kernel builds fine but boot messages do not show any attempt to detect my SATA HDD, so root mount just fails (I use GEOM UFS labels in my /etc/fstab). Typing ? at "mounroot" prompt I see only daX devices standing for my USB cardreader and no device for HDD. It seems I miss ada(4) device and I cannot find it in 8.0 - not ada.ko nor "device ada".
