Public bug reported:

Binary package hint: linux-image-2.6.26-3-generic

After grub selection there is no any output to screen till gdm start.
This happens if VESA mode selected in grub command (vga=792 for example). VGA 
modes work well.

This problem exists only in 2.6.26-3 kernel.
As I can see kernel had switched to uvesafb from vesafb.

There is another bug (https://bugs.launchpad.net/ubuntu/+source/linux-
meta/+bug/189621) about missing v86d, which is needed for uvesafb to
work correctly.
