I want to use framebuffered console on my nvidia GeforceDDR. Because I'm using X with nvidias driver, I can't use rivafb. So I compiled vesafb into my kernel. At bootup I get this error:

I was getting same error when I used vga=<whatever> while expected option was video=xxxfb,1280x1024@75 or something of that kind. I suggest you check documentation for your fb type to see how exactly to set the resolution. using vga= seems to become obsolete for many cards.

that may be the trouble.
Also there is vesafb-tng patch in some kernels. In that case use of vga=ask would cause troubles... So I suggest you check grub again.
