Sounds like thats your answer then.  As you've proven, ACPI S3 won't
work on your system for some reason.  If you contact the ACPI devs they
may be able to give you some debug code to run to get output over, say,
the parport (typical output method used), but you'll have to keep
pulling the cmos battery every time it bricks on you.

The only non-acpi suspend alternatives are APM (which you said you
didn't want to use) and one of the swsusp variants (swsusp1 in the
kernel or swsusp2 patches).  I find the delay of writing to disk is more
than made up for by the convenience of not having to resume all my
previous work (I keep an obscene number of apps and terminals open).  If
you don't find the same, which it seems you don't, you're relegated to
halting and restarting every time.
