I had a problem a while back with my laptop viewing my virtual consoles 
they were black but the Gui console was ok. It also uses a nVidia 
graphic card. There was a bug in the nVidia driver. It eventual was 
fixed but for a while after every grub update after a kernel update I 
had to add vga=791 on my kernal line in my grub menu.lst file. It looked 
like this.

title Ubuntu, kernel 2.6.15-22-386
root (hd0,4)
kernel /boot/vmlinuz-2.6.15-22-386 root=/dev/hda5 ro quiet splash vga=791
initrd /boot/initrd.img-2.6.15-22-386
savedefault
boot

 The normal display of 640X480 wouldn't display. The vga=791 set the 
display to 1280X1024 which worked.

there are other display modes

(This is notes on vesa frame buffer settings. Got from Linus Annoyances 
For Geeks. Today's date is 6/26/2006.

Frame Buffer know-how is at 
http://www.tldp.org/HOWTO/Framebuffer-HOWTo.html  .

Table 5-3. VESA video modes

Bits    640x480    800x600    1024x76  1280x1024  1600x1200

8    769    771    773     775         796

16    785    788    791      794         798

32    786    789    792     795         799      )

I have used this on the menu.lst , for grub on the kernel line , used

vga=791 , to pass this vesa parameter to the kernel.

It would be easy to try this by editing your menu.lst grub conf. file.
