Do the actual hardware register write very early in vbl and swap the buffers in the main loop.
It doesn't hurt if the vbl set the same address several vbl in a row.
To do your own vbl routine isn't hard:
However, if your main loop suddenly need less than 1 vbl in some cases, you need to wait for vbl so you don't swap around all buffers and end up on the visible one.
