The search algorithm for require can be extended, see

-- oberdiek.luatex.lua
module("oberdiek.luatex", package.seeall)
function kpse_module_loader(module)
  local script = module .. ".lua"
  local file = kpse.find_file(script, "texmfscripts")
  if file then
    local loader, error = loadfile(file)
    if loader then
      texio.write_nl("(" .. file .. ")")
      return loader
    return "\n\t[oberdiek.luatex.kpse_module_loader] Loading error:\n\t"
           .. error
  return "\n\t[oberdiek.luatex.kpse_module_loader] Search failed"
table.insert(package.loaders, kpse_module_loader)
-- end of file

However I haven't solved the problem with submodules yet.
