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 ledtrig-heartbeat.
Gr{oetje,eeting}s,
