request: bring back framebuffer

Re: https://community.ipfire.org/t/increase-monitor-resolution/6205/23

At times, when I go to customer sites, all I can access is the ipfire console with a wide monitor 1920x1080. In the past I was able to modify GRUB and increase resolution so I can see messages as wide as possible. I brought up the issue to the Community site and was told framebuffer was removed on cu157 (it existed in cu156). It would be a waste to lose all that work that someone did in cu156. And I doubt it adds many MB to the core system. So my request is to bring back the framebuffer capability. Thank you, Paul
