I posted a patch under the thread titled "Console Rotation" 2 days ago. 
It should support rotation in 3 additional directions (90, 180 and 270
degrees).  As far as fb-based apps, they have to do the rotation on
their own.  XFbdev in 4.2.0 already does that.

It should not be too difficult to add per-driver support once the

Can't this be moved up to generic code, so we don't have to modify all drivers?

rotation wrappers are implemented.  The main requirement is that the
driver must support the drawing primitives (xxxfillrect, xxxcopyarea,
xxximageblit -- main reason I like the primitives is because you can do
a lot of fancy things with minimal code change).  I already did this
with VESA fb, and it required less than 100 lines of code.

Since in the end all drivers will, this is not a real issue.
