Yes, it would be straightforward to add commodity hardware support to
olpc-os-builder.  Add kernel and boot loader.  Add some sort of

But we have SoaS, and SoaS works fine on commodity hardware, so why
bother with olpc-os-builder?

Because olpc-update?  Nobody uses it.

Because preinstalled activities?  SoaS can do that too.
