This patch fixes the 'fbcon=map:<option>" of fbcon.  (This option has been
present since 2.4, but got broken in 2.6). This particular option tells
fbcon what framebuffer device gets mapped to what console. Syntax is:

	fbcon=map:abcd...

	where a, b, c, d,... are framebuffer numbers as it would
	appear in /proc/fb.

Given only 2 valid fbdevs, 0 and 1, if fbcon=map:0110, then:

tty1 = fb0
tty2 = fb1
tty3 = fb1
tty4 = fb0
(sequence repeats for the rest of the consoles)

If an invalid framebuffer is used, then the console will be mapped to the
first user-chosen framebuffer.  Ie: fbcon=map:102

tty1 = fb1
tty2 = fb0
tty3 = fb1 <
