CONFIG_FRAMEBUFFER_CONSOLE_DETECT_PRIMARY=y
No luck here, console is still blank when starting and retain the X
image when switching to consoles from X.  I suppose it doesn't help to
have it as a module, it's still getting loaded a executed.  It's too
bad though, I've measured it to be 13 times slower than the VGA text
console on dumping a whole bunch of text to the screen.
