II Issue: Advertisement icons are misaligned in footer. Also some advertisement icons are not getting displayed.
III Conclusion: display: inline should display the element inside the current block on the same line. Only IE and FF seems to be displaying the two block level elements in the same line.
IV Other browsers:
Opera: not ok
IE 7: ok

display: inline wraps when there is too much content to fit on a line. This doesn't sound like a bug. Your reduction behaves identically in firefox and WebKit.
If you feel there is an issue please provide a reduction that demonstrates the difference between the browsers.
