In this case, You should avoid flashing vmlinuz from kernel-power, cause You'll lack sufficient modules for it, at least AFAIK.

Still, it's possible to flash framebuffer kernel (just by using flasher-3.5), but the package You've sent me via mail is only "kernel-framebuffer-flasher", not "kernel-framebuffer". flasher is only for flashing already installed kernel-framebuffer (kernel-framebuffer actually contains vmlinuz file, flasher only flashes it, just like flasher-3.5).

guy that sens you kernel-framebuffer-flasher, probably also have kernel-framebuffer, he just doesn't realize that, cause kernel-framebuffer was downloaded automatically (it's dependency of kernel-framebuffer-flasher). Get in contact with him, explain the situation, and he'll be probably able to help You.

Furthermore, if he still got framebuffer kernel installed, he got it's plain vmlinuz image in /boot/. So, using this image will also do (but, he need to be 100% sure that it's really vmlinuz of framebuffer kernel... Flashing another one won't blow anything, but won't help either).
