[ good list ]

This is wonderful. I (and some co-conspirators) started a similar
project, and put up patches at www.arnor.net/linuxlogo . But yours is up
to date, and ours is not (I was waiting until the framebuffer rewrite
was done, and then I didn't have time to catch up).

It would be great if your patch was merged. If I may offer some
suggestions... well, feature requests :-)

It would also be nice to have an option to turn off the blinking cursor
on the framebuffer. With a full-screen boot logo as used on embedded
systems, even with a serial console or console on tty2, you still get
the blinking cursor in the top corner of the screen. (at least in 2.4.x)

Other options that might be useful, but less important:
- Single logo option for SMP
- A "no logo" option, while still including framebuffer support
- Logo positioning (centered horizontally, vertically, both)
- Background and foreground text color options.

A combination of these features would make it possible to do a smaller
logo (say, 256 x 128) centered on the screen with a matching background
color that would make it look like a full-screen logo, while not
bloating the kernel image much.

Also, some simple documentation that would help beginners do a
full-screen boot logo with the console on tty2 or serial should be
included with the kernel. Lots of people want to use Linux on
"embedded" PC-based systems like kiosks, or just do this for fun on
their home computers, and doing this is confusing for beginners.

If you like, I would be happy to write documentation like this or help
in other ways.

I hope there is little resistance to merging a patch like this. If
anyone doubts the need, I can only say that despite our patches not
being kept up to date regularly, I get a lot of email about them. Also,
there are patches by other people to do things like this, some better
than others. Despite the hassle of finding and applying these patches,
people want the feature badly enough to make the effort. I see a lot
more desire for this feature than for many other worthwhile things that
are merged into the kernel...
