I can confirm this bug with busybox 1.6.0, too!
Yesterday I've posted it on #uclibc but got no answer.

[15:41] <dieter__> Hi, I've got a strange problem with busybox cp applet.
[15:41] <dieter__> If I cp a image to a /dev/fb0 on a arm linux system with
busybox cp nothing happens.
[15:41] <dieter__> with standalone cp application everything works fine.
[15:42] <dieter__> busybox version is 1.6.0 :(
[15:42] <dieter__> Does someone has any tips for me?
--- snap ---
So it looks like this bug (if so) was introduced earlier in busybox?
Here you can see a short strace of a copy:

What I don't understand (and maybe the root of the evil) is:

open("/dev/fb0", O_WRONLY|O_CREAT|O_EXCL|O_LARGEFILE, 0100744) = -1 EEXIST
(File exists)
unlink("/dev/fb0") = 0

cp sees - "ah, the file exist" and calls unlink() which deletes the "name" from
the filesystem.
After that it looks like cp creates the file new - but now as standard file and
not as char dev?
