Comment 17 for bug 447692

I confirm that on this system, removing the "splash" parameter from the kernel boot line (and routinely reconfiguring grub2) restored access to the virtual consoles Ctrl-Alt-F1.

From my non-developer's perspective, and after reading the 16 preceding comments on this thread, it appears that the solution will be obvious once we understand how the presence of the boot splash has so suddenly started disfiguring the customary virtual consoles Ctrl-Alt-F1 through F6.
