5-10 years? A better estimate would be 15-20 years. People aren't going to 
throw away perfectly fine systems and jump to new "cloud" platforms just 
because the OS they were using dropped BIOS support. They'll just stop 
updating, and likely move to something that is still supporting BIOS,  if they 
don't write their own installer and just continue using Fedora, given that 
this is an entirely artificial limitation.
