Why would they have problems coexisting?  You can mix USB and FireWire
storage devices with SCSI just fine (in the past, I've plugged a FireWire
DVD burner into my server (which uses a mix of SCSI and IDE storage) to make
backups), and they (like SATA) go through the SCSI subsystem as well.  SATA
should be no different than USB or FireWire in this regard.

If you want to control the order in which devices are enumerated, compile
into your kernel only the driver for the interface used by your boot drive
and compile the other drivers as modules.  By loading the drivers for fixed
storage (SCSI, IDE, or SATA) before the drivers for hot-pluggable storage
(USB or FireWire), you can make sure the allocations of /dev/[hs]d* nodes
don't shift around from one boot to the next.
