Yes, I guess it's a bit risky. With me, it's a brand new laptop so I assumed no drivers would be out of date and that all hardware was compatible. Fortunately I was right.
Perhaps there is a tool that will identify any potential problems. I know there is on the Vista DVD a tool that highlights problems when upgrading from XP but I haven't heard of a specific SP1 tool.
Sorry I can't be of more help.
