No, not really. Our bug reporting underrepresents reality in the general 
case. We have no idea how many subtle issues on other hardware may be 
caused by this kind of BIOS breakage. And the sheer number of people 
still running with pci=noacpi irqpoll and the like indicates that many 
users will just run with boot options rather than ever reporting the 
issue that caused them to.
