In TTYs, the penguins you see on top of the
booting process remain. Then in less, i cannot scroll
upwards, which sucks using man and like that.
How do i change that?
Disable the "Bootup logo" option in your kernel:
Device Drivers -> Graphics support -> Bootup logo
That is another issue. You need to select the pager you want with eselect:
eselect pager list
gives you a list of possible choices. The usual choice is using the
"less" tool as pager (/usr/bin/less). So simply set that with "eselect
pager set [number]". Refresh your environment (by sourcing /etc/profile
or simply logging out and back in again.)
The penguin remaining on the screen seems to be some framebuffer
witchery, like decorations or some background. The framebuffer
provided penguins scrolls fast as the system boot messages flood the

you are also able to eliminate them entirely by disabling the boot-up logo.

than he could before, if he is sincere about it and has common sense.

You're using a framebuffer driver which is either misconfigured or not
supported by your system. Most of the time it's just vesafb interacting
badly with a broken VGA BIOS; if that's the case you can try playing
with the commandline options pertaining to how scrolling is done (read
vesafb.txt under Documentation/fb in the kernel source tree)
If you have a reasonably recent intel/amd/ati/nvidia card and you're
mainly interested in text mode, the framebuffer provided by the relevant
in-kernel DRM driver is usually the best choice (and it's a hell of a
lot faster than anything using BIOS calls like VESA).
If you have older hardware, uvesafb tends to work better than vesafb in
a lot of cases, although it requires a bit of work for setting it up.
If all else fails, there is always the basic VGA text console :)
