Bug#386441: initramfs-tools: Support custom framebuffer modules

[David Härdeman <david@hardeman.nu>]

Package: initramfs-tools
Version: 0.78
Severity: minor
Tags: patch

The attached patch adds support for the "video" kernel parameter to the 
framebuffer script. This allows for the use of non-vesa/vga framebuffer 
drivers and at the same time simplifies the logic a bit.
