When I boot up to single-user mode, kldstat says:
Id Refs Address                Size Name
 1    7 0xffffffff80200000  1f2ffd0 kernel
 2    1 0xffffffff82130000    8cc90 vboxdrv.ko
 3    1 0xffffffff821be000    ff4b8 if_re.ko
 4    1 0xffffffff822be000     77e0 sem.ko
After "kldload amdgpu," it says:

But after a full boot without amdgpu, it says:
