As of this past Sunday the 4th of February, ICO is once again part of Haiku. I'm talking about the famous is_computer_on syscall, present in the BeOS source and now in Haiku's, thanks to Geist (of NewOS fame). With his commit 20069, he replaced the syscall _kern_null with _kern_is_computer_on. According to him, is_computer_on_fire is a bit harder (and dangerous too, remember, don't play with fire) to implement, since it needs something (float from kernelland) which isn't supported by Haiku at the moment. And he didn't have a fire extinguisher with him.  Still, an important milestone for Haiku and for ICO too of course :)

Thanks to Joseph for the heads up.
