I'm on an older Barebox (2015.12.0) and here splash works. I do
something like this in my env/bin/init:

        splash -x 550 -y 500 -b 0xffffff /env/logo.png
        pwm_02080000.period_ns=200000
        pwm_02080000.duty_ns=160000  
        pwm_02080000.enable=1
        fb0.enable=1
        gpio_set_value 191 1
