Bug#502056: Add support for uvesafb

["Michal Pokrywka" <mpokrywka@hoga.pl>]

Package: initramfs-tools
Version: 0.92j
Tags: patch

Uvesafb framebuffer driver needs v86d userspace program
but when fb driver is modprobed at init-top stage of initrd,
/dev/zero and /dev/mem are missing because udev have not
been run yet.

Attached patch fixes this issue.

Michal Pokrywka
