Pageflipping will work if you have a target which can pageflip.
Currently that includes fbdev (with a driver which supports it),
glide, X, dga, and when using supported child targets: palemu,
trueemu and tile.

For info about framebuffer consoles (fbdev) please see
/usr/src/linux/Documentation/fb/ and the Framebuffer-HOWTO.
But in short, yes you need a 2.2 kernel to use framebuffers on ix86.
