Well, it's not just "somehow".
It's the x86 def_config value, and it's also the default in at least the
Fedora kernels.
Probably for a very good - although these days probably historical -
reason: on older hardware, it really wasn't all that unusual to have the
serial port at other interrupts.
And Alan may point to the help text, but that doesn't really matter since
everybody clearly ignores it, and it's not what has been tested.
But yeah, we probably should disable it at least for modern machines. And
even if it doesn't autodetect the irq, "setserial" hopefully still does
work (and was always required for some machines anyway)
