Moreover, this can't really be fixed. vesa16fb and vgacon are both 
extremely limited compared to vesafb. So, forcing people to use them 
will severely cut into the usefulness of having the framebuffer there in 
the first place (on x86, at least).

Does anyone know if it's just a rePOSTing issue or something? Could it 
really not be rectified in the kernel?

The other evolving problem is that many newer (especially nVidia) cards 
don't support vesafb at all, and the more-hardware-specific framebuffers 
aren't as kind to power management.
