"harmless" isn't a word i'd use :)

So what exactly in the fbcon code is causing those? In my mind, at least,
an error is either a sign of A) sloppy/careless code or B) a Security
hole from hell. I'm moderately worried that some genius hacker will come
up with an exploit and use it to have some midnight fun :)

Just to voice an opinion, fixing those would suuuure make me more likely
to trust the stability and security of the fbcon layer. :) if the rest
of the kernel isn't griping and it compiles cleanly, then it "probably"
works fairly well. :)

then again, i'm probably being a little bit anal about this, and should
probably reinsert my foot in my mouth. :)
