Linux frame buffer console help needed

I want to learn a little about using a linux framebuffer console & would appreciate some help. So far all I have been able to do is start up vtcon1 as a frambuffer device after booting vtcon0 as a vga device.

Here is what I do to start my vtcon1 FB console:
boot to init s or init 3
modprobe fbcon
modprobe vga16fb

Once the fbcon1 frame buffer console is started, I can execute a few simple "fbset" commands:
fbset --show ...640x480-60 is displayed
fbset --info
fbset -move < direction >

Also, prior to starting a FB console, I used the vbetool program to create the file vga.state but when I try to detach from vtcon1 & return to my vtcon0 my screen goes black & I am forced the (ctrl-alt-del) reboot.

vbetool vgastate save > vga.state
vbetoo vbestate restore < vga.state && echo 0 > /sysclass/vtconsole/vtcon1/bind

This is all I know about using a FB console. I'd like to know how to change the screen resolution & display a simple graphic
file. If anyone can help, it would be appreciated. Thank you.
