I'm just sitting at the office waiting for a call and you got me curious. I'll do some Googling for you at no charge.

I am not aware that LN produces a roller bearing replacement for the IMS. There is one that they offer on their web site as an "economical alternative to the ceramic roller bearing". But it appears that it is actually createded by RND Engines rather than LN.
LNE states: "We did develop a version that utilized a cylindrical roller bearing with thrust ring, but it never made it from testing to production for the primary reason that Porsche chose a ball bearing originally, not a roller."

There is some interesting discussion of OTHER roller bearings here:

and here:

By my read it looks like the biggest problem with the roller bearings is dealing with thrust force. It looks like that one, sold on the LN web site, handles the load well and does not require an oil feed. Oil feed implementations may vary in success, so I like that this one does not need it. It costs the same as the ceramic ball bearing replacements.

I have no experience with it, but it looks like a good 4 year/50,000 mile choice.
