We are a Lenovo shop and leverage R&R. R&R to my knowledge has a hidden service partition which I believe is already encrypted(this may be an option, not certain) I would avoid encrypting this service partition as like you stated you can no longer use R&R. When I test on a WinXP system I may be able to shed more light on this topic. Currently I'm testing with Windows 7 32/64bit. Thus far its working fairly well.
