Ah. What's that for? Does qemu change its behaviour depending on the
kernel version? Ah, something to do with blacklisting. But is the
Linux kernel version the most useful value here? Shouldn't there be
some kind of separate version number? And what's the blacklisting stuff
for anyway?

Wow, this interface is perverse. It reuses the same IO port but changes
function depending on the size of the IO? Again, wow.
