Hi, I am attempting to do something similar on a new board. How did you change the the video mode for VFB? I have tried modifying the vfb_default screen info in vfb.c, and I use the boot param video=vfb: and the fb always comes up in 640x400 mode. I tried setting params on boot (for example: video=vfb:320x240-24@60), but still nothing changes the mode.
