Thank you for your detailed explanation in the patch.

I know.  I was surprised that my patch fixed something else, but now we
know that it didn't.  It's better when patches don't have unexpected
effects even if the effects are positive :)

I simply tried another approach to pacify the resource checker.

However, there is some difference.  nvidiafb cannot access the
resources if IORESOURCE_BUSY is used.

It's not that it matters for me.  nvidiafb fails on my hardware anyway
and I don't need it when I already have simplefb and nouveau.  But I
think we should have a closer look why it fails and what other drivers
may fail.
