I read about 75% of the pages on this thread and I have yet to come across any sort of guide on how to install Lion. Here are some specs that might be pertinent in getting me updated to Lion

AMD Phenom X4 64
Model: 2
Family: 16
ATI Radeon HD 4650 (was a pain to get this working in 10.6.8..guessing lion won't be better)
I use apple's usb to ethernet adapter for internet (Realtek 8185L wifi and Yukon 88e8071 are installed but couldn't find a fix to get them working)
4GB DDR2 Ram (have 4 more Gigs I'd like to use if anyone knows a fix for this in lion or even snow leopard)


I have no access to the app store in snow leopard (I've tried every fix possible with no luck..if you have new ideas here i'm listening ) so I can't get the update to lion that way. I don't have an Intel PC to work off of so that route is out. Wasn't sure if I would be able to download a retail copy of lion along with some combo updates and get the install working that way? Also I am not sure how I would go about applying the kernel (once I know which one I need to download). I used nawcoms ModCD to get my snow leopard install working (if that helps at all). Thanks!!
