Each /dev/fbX represents another video driver. If you use just vesafb then
you have just /dev/fb0. When you insert kgicon.o you will get /dev/fb1.

Yep. Vesafb CAN NOT chnage modes after booting.

Thats right. By devices I assume you mean console. In this case /dev/fb0
is vesafb and /dev/fb1 is kgicon.

con2fbmap maps the framebuffer device to a console. If I remember right
the command line goes con2fbmap "console number" "framebuffer device".
If console number is 0 it maps all the consoles to the framebuffer device
you gave on the command line. So con2fbmap 0 1 maps all the console
devices to the first framebuffer device which is vesafb. Now a con2fbmap 0
2 would map all consoles to /dev/fb1 which is kgicon. If you are on the
first VT you problem want to use kgicon just on that terminal. Then just
do a con2fbmap 1 2

Ummm.... Hey guys how many changes have you made to CVS since the beta?
