Yes, *please*! That would solve my biggest concern. As far as I can see that's only 2 commits to be reverted: b3ec8cdf457e - "fbdev: Garbage collect fbdev scrolling acceleration, part = 1 (from TODO list)" 39aead8373b3 - "fbcon: Disable accelerated scrolling"for-next-next I think both were not related to any 0-day bug reports (but again, I might= be wrong).
