For business use (when you're creating a system to sell to others, whether it's small/embedded or a large dedicated purpose server) the customizations make more sense. On the other hardware (arm, mips, powerpc, etc) I think the modular approach makes more sense. There are certain things that are required for every arm kernel. There are other things that change based on major architecture (armv4 vs. armv6 for example; the same sorts of distinctions as i386 vs amd64). There are also things that are very specific to the chip or system-on-a-chip the kernel is for. -- Ian
