I did the upgrade via urpmi and my system was pretty much intact, other than some files not being able to be installed during the upgrade process. Grub didn't pick up my Vista partition, and my Ethernet card was not detected due to supprt being disabled since it is one of the effect cards, so I had no internet connection, so I reinstalled 2008.1 Powerpack edition. Hope this corruption issue with the ethernet cards gets fixed soon!
