If you prefer your own style of asking Wait, I found the answer from Gerd from our last conversation! See attachment. As stated, nothing will break if vesafb is just available in the kernel. If a user enables it, sHe should know whether the video card supports it (most do). In contrary, when the user switches from existing, vesafb-enabled configuration to a Xu's kernel, he only gets a _black screen_. No warnings, no hints.

No. It's not used by default, just saying 'Y' to vesafb doesn't activate it at boot time. fbcon+vesafb comes into play if you pass a vesa graphics mode as vga=xx argument to the kernel. > - is there is a simple way to make it modularize the driver? No. vesafb depends on the VGA BIOS activating the graphics mode (which is done in real mode startup code). Thus it works on nearly all graphics cards on earth, but it also has a few drawbacks: Limited to flickering 60Hz standard vesa modes, no mode switching at runtime, it's very slow, ... > If no, is a replacement in development? No. Some people tried to play tricks (use vm86 to call the BIOS) to overcome the limitation mentioned above, but that isn't trivial.
