I love my Void Linux’ framebuffer only setup, but once I spawn X.org, SDL2 gets borked with some udev function. If not, SDL2 games and emulators work beatifully under KMS/fbdev. Pcsx-rearmed should work under the framebuffer except it borks out the whole rendering on KMS. I may have to set some SDL2 initialisation flag. Sadly mednafen is too slow for PSX.
