For this problem we have some articles in our Gentoo Forum.

Between 5.10.x and 5.15.x there was a change:

You dont have a "Simple FB" in your old directory (when doing "make
menuconfig"); instead there is a new entry which leads to this in your .config:

CONFIG_SYSFB_SIMPLEFB=y

(Searching for "SIMPLE" in your .config gives you only this one +
"CONFIG_DRM_SIMPLEDRM=y". If you have the old entry also in your .config, then
you have not done "make oldconfig").

The "new" simpleFB is here:

Device Drivers  --->
  Graphics support  --->
    [*] Simple framebuffer driver

The old one was here:

Device Drivers  --->
  Graphics support  --->
    Frame buffer Devices  --->
      [*] Support for frame buffer devices  --->
