I don't know if this would work, but you might be able to create a running total that would at least get you the current page number. Because of the way Crystal processes data, I doubt you'll ever be able to get the total page count.
First, create a formula that just contains the number 1. I'll call it PageCount.
Create a Running Total:
Type of Summary: Sum
Evaluate: Use Formula: pagenumber > previous(pagenumber)
Reset: Never
