Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!

+config VT
+ bool "Virtual terminal" if EMBEDDED
+ select INPUT
+ default y if !VIOCONS
+ ---help---
+ If you say Y here, you will get support for terminal devices with
+ display and keyboard devices. These are called "virtual" because you
+ can run several virtual terminals (also called virtual consoles) on
+ one physical terminal. This is rather useful, for example one
+ virtual terminal can collect system messages and warnings, another
+ one can be used for a text-mode user session, and a third could run
+ an X session, all in parallel. Switching between virtual terminals
+ is done with certain key combinations, usually Alt-<function key>.
+
+ The setterm command ("man setterm") can be used to change the
+ properties (such as colors or beeping) of a virtual terminal. The
+ man page console_codes(4) ("man console_codes") contains the special
+ character sequences that can be used to change those properties
+ directly. The fonts used on virtual terminals can be changed with
+ the setfont ("man setfont") command and the key bindings are defined
+ with the loadkeys ("man loadkeys") command.
+
+ You need at least one virtual terminal device in order to make use
+ of your keyboard and monitor. Therefore, only people configuring an
+ embedded system would want to say N here in order to save some
+ memory; the only way to log into such a system is then via a serial
+ or network connection.
+
+ If unsure, say Y, or else you won't be able to do much with your new
+ shiny Linux system :-)
+
+config VT_CONSOLE
+ bool "Support for console on virtual terminal" if EMBEDDED
+ depends on VT
+ default y
+ ---help---
+ The system console is the device which receives all kernel messages
+ and warnings and which allows logins in single user mode. If you
+ answer Y here, a virtual terminal (the device used to interact with
+ a physical terminal) can be used as system console. This is the most
+ common mode of operations, so you should say Y here unless you want
+ the kernel messages be output only to a serial port (in which case
+ you should say Y to "Console on serial port", below).
+
+ If you do say Y here, by default the currently visible virtual
+ terminal (/dev/tty0) will be used as system console. You can change
+ that with a kernel command line option such as "console=tty3" which
+ would use the third virtual terminal as system console. (Try "man
+ bootparam" or see the documentation of your boot loader (lilo or
+ loadlin) about how to pass options to the kernel at boot time.)

+ which aren't supported using the standard "dumb" serial driver.
+ This includes intelligent serial boards such as Cyclades,
+ Digiboards, etc. These are usually used for systems that need many
+ serial ports because they serve many terminals or dial-in
+ connections.
+
+ Note that the answer to this question won't directly affect the
