It can be enabled by putting "bios_patching true" in the VESA settings file. This patching does not work yet on modern hardware, but the detection code to decide if we should try patching still says it found the modetables. In this situation we can crash the BIOS or other weird things can happen. To avoid these problems, and because VESA is supposed to be the failsafe option, disable this code by default, and let people who want to experiment with it first enable it in the settings file. Should fix #17633.
