Actually, the "Remove Blogname from title" feature affects both posts and pages. This can be good for posts as they tend to have longer titles. It would be nice if there is an option to keep it for pages though!
In 3.1 I'm going to add a per-page/post/CPT options to remove the title additions.
It requires more manual work than a global on/off switch that affects multiple CPT, but it's far easier to implement.
