Hello
I love my matroxfb (1024x768-8bpp at 85Hz :) ); and I am known to boot
into several different kernels; however, between the speed of modern
computers and the >flash< as the monitor changes resolutions, the kernel
version details, as output by "printk(kernel_banner);" in init/main.c
scroll off the screen even before they register in my vision.
Hence I offer this simple patch; purely cosmetic without any side
effects[1] that I can see, which takes UTS_RELEASE, and displays it on
the screen in the top left corner, above the boot penguin.
Due to it's location, the text persists along with the penguin, while
boot messages scroll past.
Applies cleanly to ac21 and ac22, and 2.2.14 (as ships with RedHat 6.2)
The downsides are a few lines more code, and one line less screen
realestate on boot.
If anyone wants to try the patch and comment / report bugs, I'd be more
than grateful to hear from you.
If anyone wants to flame, well, I believe my /dev/null is empty these
days.
[1] Murphy's Law requires at least one side effect for saying that.
