Ok, so I lied miserably. First, it’s not off by default, I commented
SAVE_VBE_STATE=true out way-back-when I did my first attempt to fix
suspend and forgot. Second, commenting it out and acutally setting it
to false are two very, very distinct things.

After some more hit-or-misses and and offline input from my friend
I actually arrived at a working suspend; the catch is to turn off the
splash kernel parameter (bye bye you nice Ubuntu bootsplash) and doing
the following to the original /etc/default/acpi-support:

-#ACPI_SLEEP=true
+ACPI_SLEEP=true

-SAVE_VBE_STATE=true
+SAVE_VBE_STATE=false

-POST_VIDEO=true
+POST_VIDEO=false

-USE_DPMS=true
+USE_DPMS=false

Thanks again, Peter, for providing the right acpi-support fixes!
