I've committed a change that changes the default video mode for normal 
installs (using the newt frontend) to vga=788, which forces the VESA 
framebuffer. Tested on my own HP 2510p.

The change should take effect in the next daily and weekly builds.

Here's the commit log for the change:

Change default video mode for i386/amd64 to vga=788 for the "newt" frontend

This forces the framebuffer to VESA and will thereby solve problems 
reported on various HP notebooks with the vga16fb driver (#471505).

It also increases the screen size (to 600x800, which is still quite
conservative) and thus allows more information to be displayed. Note that
dialogs should continue to be designed to work with 480x640 as other
architectures may still use that as a default, and for network-console.

vga=788 is the same video mode we use for the gtk frontend and as we've 
seen very few reports of that failing the change should be safe, but it is
still somewhat experimental.
