I had 10.6.3 working on my laptop with DSDT and loved it.
(compiled my dsdt with dsdtSE through 10.5.8)

I cleaned up the DSDT myself and had no problems with my machine (honest truth!). I recently put new Ram in my machine and this is when it gets weird. I have 3 OS's (10.6.3, 10.5.8, Win7) all on separate drives. Leopard and 7 Load just fine but 10.6.3 did not load. Snow Leopard would get to white loading screen but no progress circle.

After talking to some very helpful people someone requested I remove my DSDT from my folder. Once removed.. Progress circle came back but still would not kick over.

I was told that it could be my DSDT that was causing this issue with the ram. I am wondering if this idea has any merit? My DSDT from only had 4 warnings (3 return values to 0 and 1 all alpha/numeric). I don't see how these could cause the DSDT to not load snow leopard. However, the DSDT that was I was using was made when I had the original RAM in the machine.

Any thoughts, opinions or advice is greatly appreciated.
