Install bukkitforge 1.5.1-282 to the latest released tekkit main 1.0.5 server then you can use bukkit pluggins (some don't seem to want to work like tim the enchanter but that's not a huge loss) put the jar into the coremods folder on the server and boot it on up.. works great for me hope that helped.

I'm using the all the mods, none disabled on a Tekkit 1.0.5 server and BukkitForge-1.5.1-282.jar in the coremods folder works just fine only having one minor issue with it somewhere with one or more of the mods all of the normal enchantment ids that normally work with tim the enchanter are invalid which is weird cause the ids are still the same aside form added enchants from some mods. but anyways hope that helps your issue.
