commit 15df28699b28d6b49dc305040c4e26a9553df07a upstream.
A regression was reported to me recently whereby /dev/fb0 had disappeared from a PowerBook G3 Series "Wallstreet". The problem shows up when the "video=ofonly" parameter is passed to the kernel, which is what the bootloader does when "no video driver" is selected. The cause of the problem is the "offb" string comparison, which got mangled when it got refactored. Fix it.
