yeah, we / I chose to make only AHCI builtin as pretty much all new hw
coming out theese days are ahci-compliant, so it works out of the box.
And to not bloat the kernel the "rest of the hw support" got left as
modules.
Now this feature "booting without initrd" is obviously targetted for
laptops/netbooks & desktops where people care about fast boot.
For servers (& bigger workstations) where you rely on SCSI / SAS / FC /
.... you still need initrds, and usually you dont really care if a
boot take a little longer.
