What do you mean enable a vesa3 driver, if you mean use vesa3 from your OS, then yes, here are some bootable demos i have made, that may help:

All you need do to use vesa3 (which is also compatable with vesa2), is test for it and if found, use the vesa3 ext.

thanks a lot... I want to know something else, if it's possible:
- how can I make a mouse PS/2 driver for an OS and how to transform it
into an interrupt?
- how is it possible to make a own font set? does it need to be in memory any time it is used?

You can use Bios fonts, but if you are making your own, than they need to be loaded in memory or they will be slow to use.
One char will be simular to this

Code:

DB 0FFH,0FFH,0FFH,0FFH,0FFH,0C3H,099H,0BDH,0BDH,099H,0C3H,0FFH,0FFH,0FFH,0FFH,0FFH

you can get a font maker program from bubach site: http://bos.asmhackers.net/docs/vga_without_bios/snippet_3/
And info on mouse and setting up int's etc here:
