Do you have serial console, or can you ssh in, or can you type blindly? Can you get dmesg out that way? If not, can you reboot (without full poweroff), enter userconf, disable i915drmkms, disable radeon, disable nouveau, and get dmesg from the previous boot? > If the kernel tries to select mode 1-3, that would explain the dark > screen. Is it a possible behavior? How can I change it? More likely something about the drm driver is hosed.
