Honestly, I have no idea, but it shouldn't hurt to try. Also, keep in mind, that since few versions, kernel-power also got framebuffer (yet, You need to modprobe it early during boot process, afaik framebuffer kernel had it hard-coded somewhere).

As for framebuffer kernel (specific one), all my experiences with it are from second-hand - i.e. from reading TMO< never used it myself, so I know as much as You now, or even less I'm using viewable framebuffer output on every boot, but through kernel-power and modprobe fbcon.

It mean, that You need to experiment on your own - of course, any feedback from Your struggles is highly appreciated. Successful attempt could be documented and help others
