Fix problem with legacy mipmap code on legacy ATI radeon X cards.

Browse Source 
This was patch #285 from Danyal Zia and is about old radeon cards not supporting npot textures despite claiming so I think.
Was never applied as needed some rewrite first (did string-comparisons a bit too often), so got stuck on patch-tracker.
Well, lets hope this fixes it in case anyone ever needs that specific combination ever again ;-)
