Well, then we just do it on systems that do have support in their firmware. For starters that would be: alpha, sparc, sparc64, mips and hppa, possibly arm and m68k as well. The only architecture which really has problems with this is the PC (not PS/2: they have a protected mode BIOS as far as i know), but that should be solveable with some ingenuity and real-mode callbacks... And i wouldn't mind adding an old 300-500 MB IDE disk to my servers solely for the purpose of capturing crash dumps if that were necessary.

Well, but other people have. So IMHO we should add the possibility of generating kernel dumps where possible. Just make it an option, so people feeling uncomfortable about it could disable it...
