Well, I found out templates stored themselves at:
"C:\Users\[UserName]\Documents\Visual Studio 2008\Templates\ProjectTemplates\Visual C#"
after installing them, so I just cut/paste them into:
"C:\Users\[UserName]\Documents\Visual Studio 2005\Templates\ProjectTemplates\Visual C#"
And as assumed they were removed from VC# 2008 templates and are now in VC# 2005 project templates (took a while to load the first time.)
EDIT: I use Vista btw, so it should be in My Documents for XP users i think.
