No.

Seems no.
1) console developing is nightmare.
2) 99% of testers or endusers use multiple X servers instead of multiple te=

mode consoles - multiple text mode became nuty developers trick.
3)I do not know how to work "terminal emulation".

Linux is so flexible. Obvious reach same result in very different ways.

Each fb device (/dev/fbXX) assigned with separate console. Each separate
console may have keyboard device. Last working is 2.6.13
http://www.ltn.lv/~aivils/files/ruby-2.6.13-A0.diff.bz2
Under 2.6.13 kenel exists option
dumbcon=3D3:4
where 3 is count of dummy consoles, 4 is TTY count per single dummy console
As result
VGA have tty1-tty16
dummy 1 have tty17-tty20
dummy 2 have tty21-tty24
dummy 3 have tty25-tty28

Probably someone load fb dev driver, which creates /dev/fb0 - /dev/fb3,
after fbcon module loading these fb devices are assigned :
fb0 takes over VGA - tty1-tty16
fb1 takes over dummy 1 - tty17-tty20
fb2 - tty21-tty24
fb3 - tty25-tty28

If system operator will allow login via fb1-fb3 , then must be started
according login processes like mingetty. Line from /etc/inittab
<skip>
17:2345:respawn:/sbin/mingetty tty17
<skip>

Keyboards are connected to console automatic. 1st connect to VGA,
2nd to dummy 1, 3rd to dummy 2, ...

Special device /dev/tty0 seems will not work proper.
