Page flipping on LFB in protected mode...how??!?!

Hello everybody,
I am messing around with VESA graphic modes. I started
writting my own OS from scratch as a personal project and I took
a tangent into graphics. I already implanted Bresenham's line drawing
algorithm but I can't for the life of me find enough information about
page flipping.
I am running my kernel in protected mode. Is anyone on here aware of
how I can do page flipping or where I can find the information I need
to accomplish this. I would be great if I didn't have to come out of
protected mode. Coming back to real mode to flip pages through the BIOS
to finally go back to protected mode to then again redo the same thing
again ad infinitum is not favorably 'drawing' my attention.
I am using VESA mode 118h in linear mode (1024x768x24)
Regards
Jean-François Michaud
