disable fbcon in Debian Wheezy (Live)?

[Ivan Shmakov <ivan@gray.siamics.net>]

	How do I disable fbcon in Debian Wheezy?  I'm using a custom
	Debian Live image, and it switches to fbcon as soon as it can
	get to the modules!

	I've Google'd a bit, but the virtually the only recommendation
	I've found is to add fbcon=map:9 to the kernel command line.
	Unfortunately, instead of leaving the VGA console alone, it
	apparently completely deactivates it (the display enters a power
	saving mode.)

	As a work-around, I can boot with "emergency", and remove
	/lib/modules/2.6.39-2-amd64/kernel/drivers/{gpu,video}/.  Yet,
	I'd prefer for a less radical solution.

	(And I wonder, what process launches modprobe(8) on these
	modules, and is there a way to disable it?)

	TIA.
