If I switch VCs, then switch back, the text has been re-arranged, the cursor is often invisible, and sometimes a page or two of new text must be written before anything starts to show up on the screen again. Experimenting shows that setting VYRES = YRES works around this problem.
The second problem is of course the register contents issue when returning from certain graphics programs (e.g. X+fglr) to text mode.. I rather like your idea of doing a re-init when switching from KD_GRAPHICS to KD_TEXT, as the monitor blank during resolution switch will likely overshadow the re-init process.
