The choir is listening ;-)

For Amiga, that would require writing a real GPIO driver (modifying
gpio-mmio?) for the CIAs, and converting its users (amiflop, amijoy,
amimouse, parport_amiga, amiserial, and dmasound_paula) from direct CIA
register access to GPIO access (mctrl_gpio for amiserial)).
Note that the heartbeat LED is shared by heartbeat and audio.

An interim solution might be to just write a simple gpio driver for the
single CIA pin driving the heartbeat LED, allowing the user to set up

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
