I am running Edgy, and the VESA framebuffer is there... here's the                                                                                           
output from 'dmesg | grep framebuffer':

   [17179573.824000] fb0: VESA VGA frame buffer device                                                                                                       
I added 'vga=795' to the following line in /boot/grub/menu.lst...                                                                                            
   # defoptions=quiet splash vga=795                                                                                                                         
... and then ran 'sudo update-grub'                                                                                                                          
Framebuffer console works fine!                                                                                                                              
I am _fairly_ certain I did this on a Feisty install as well, but since I                                                                                    
switched back to Edgy, I can't be sure.
