Hooray!  Maybe I can shove it into -CURRENT...

That's wierd (and also not weird).../etc/rc.suspend (at least on my -CURRENT r267519) doesn't even appear to use the '1' argument, and it's just calling /usr/sbin/zzz  with the 'apm' argument (which I believe still does an ACPI suspend).  My patch is an ACPI patch anyway.

People on this list have been wrangling with the Intel driver, there might be fixes for what you're seeing.
