And for reference, tty2 where my getty is:
speed 38400 baud; rows 30; columns 80; line = 0;
intr = ^C; quit = ^\; erase = ^?; kill = ^U; eof = ^D; eol = <undef>; eol2 =
<undef>; swtch = <undef>; start = ^Q; stop = ^S; susp = ^Z;

isig -icanon -iexten -echo echoe echok -echonl -noflsh -xcase -tostop
-echoprt echoctl echoke

And tty1 after exiting plymouth:
root at 000c29af1815:~# plymouth quit
root at 000c29af1815:~# stty -a --file=/dev/tty1
speed 38400 baud; rows 30; columns 80; line = 0;
intr = ^C; quit = ^\; erase = ^?; kill = ^U; eof = ^D; eol = <undef>; eol2 =
<undef>; swtch = <undef>; start = ^Q; stop = ^S; susp = ^Z;
rprnt = ^R; werase = ^W; lnext = ^V; flush = ^O; min = 1; time = 0;

Mmhh. This is really going to be difficult. See, I have a live distro with
some proprietary software in, a lot of customs packages, in a prototype
form, that is built with a complex sequence of Makefiles and scripts...
Mostly is ressembles a debian squeeze and a debian-live initramfs. Also, it
lacks many packages and typical binaries found on a normal distro, the user
will never see a shell on it, it is mostly remote-controlled by a cluster
admin CLI.

But I'd be glad to help as much as I can.
