I can't help you regarding the long range PCR issue, but I have tried PCR 
cloning of a promoter region with no success.  My promoter had inverted 
repeats in it (not uncommon really) and a high GC content (not uncommon 
either) and it would not PCR.  We wound up subcloning it from a genomic clone 
directly after wasting 2.5 months on PCR in it's infinite and seductive
