I'm assuming you don't mean "lpm," since to me that means "lines per
meter." I'm assuming you mean "lines per millimetre."
As for the scanners, I suspect the one I own (the Polaroid SprintScan 4000)
is already pushing the practical limits of most films -- in many instances,
I can already resolve *grain* in the film, leading me to believe that 4000
lpi (approx. 158 lpmm) is about as much as you could ever usefully use.
I'm surprised that any additional info would be available at 8000 lpi --
even drum-scanned output doesn't normally go that high, and that allows for
extremely high resolution four- or seven-colour separations and printing.
