Since 2.5.61 at least swsusp doesn't work here, with or without S4bios. It
lists a heap of processes entering the refrigerator, then prints '=|' and
moves one line downwards, cursor blinking on an empty line.

Nothing appears to happen then, except that if I press alt-f7, my screen
blanks as if X is still partly alive. Alt-SysRQ also works and shows heaps
of processes, most of them with 'refrigerator' somewhere in their traceback.

Nothing is written to disk however.

I try to suspend with "echo 4 > /proc/acpi/sleep".

From dmesg on bootup:
