Want to make use of the framebuffer.

(Hopefully I have posted this in the right subforum.)
I have a hp nc6220 laptop with 915GM graphics and kernel module settings enabled. I'd like to make more use of it. What do you use a framebuffer for?

There is a load of fonts in /usr/share/kbd/consolefonts
I want utf8. How do I get that? What fonts work with utf8? I use setfont to see the various terminus fonts. How can I see which font I'm currently using?

What (graphical or ncurses) apps can I run in a framebuffer? I know of gpm, links -g, htop, weechat, finch. 

Is qingy only for DirectFB or can it be used with KMS? Is there an alternative to qingy?

I get no video with mplayer in the framebuffer:
mplayer -ao aa ascii_pr0nz.mp4

MPlayer UNKNOWN-4.4.0 (C) 2000-2009 MPlayer Team
137 audio & 296 video codecs

...and the three last rows are spammed until I stop mplayer.

I'd like more scrollback than 156 rows in the virtual console.
If i do

for i in {157..1}; do echo $i ; done

I can't read the line that says 157. A screenful is currently 65 lines, including the prompt. I have seen suggestions to recompile the kernel with VGACON_SOFT_SCROLLBACK VGACON_SOFT_SCROLLBACK_SIZE set. Maybe there's a KMS way to accomplish better scrollback without recompiling the kernel? With 2Gb RAM there is memory to spare.

Re: Want to make use of the framebuffer.

Sorry, I used the wrong mplayer options. It should be "mplayer -vo aa videofile". I got it to work somewhat with "mplayer -vo caca file" that uses colored ascii output. If I could stop the heavy flicker I would be satisfied with the video part. Maybe I'll try crossposting later

FQingy currently doesn't work if KMS is enabled. More info can be found here:
