If I compile framebuffer and video drivers as modules then panic happens earlier - at initramfs stage or before that. I can't say for sure, because currently I'm unable to use serial console.

I guess that in this case udev load video modules (radeon, ttm, etc) at initramfs stage so that's why it crashes earlier. My initramfs does not contain other modules that needs to be load.

I've just tested gentoo-sources-3.7.3. No problem with it.
