User-space programs that use framebuffer directly can use them.  I was
writing a simple framebuffer virtual terminal (using libfreetype for
fonts; like fbterm); scrolling and painting boxes would be faster if
there was someway of using hardware accelerated operations.  I think
other similar programs can benefit, too.
