Open the CR2 file in a decent text editor (I use EditPad, myself), then search-and-replace all instances of:

vertsPerHair 8

with

vertsPerHair 7

Save the file back into the library, and the fur should render properly in P8 now.

I cleaned up a few other things while poking around -- the hair and center-of-mass props have unnecessary morph channels, for instance, and I noticed redundant hairGrowthGroups that seem to serve no purpose -- but as far as I can tell, the vertsPerHair lines are the only real issue.
