Hi!
I finally tested everything possible and double/triple checked the scripts and it came down to the very simple solution:
vbetool is evil is evil is evil
I already had vbetool savestate disabled but there was still a call to vbetool dpms in the scripts.
After removing that too I am back to normal again, i.e. I use s3_bios option and nothing else to get video back (BTW: no framebuffer console, plain VGA text). According to /proc/acpi/video/VID/POST_info:
<not supported>
I have to use s3_bios since the BIOS does ot provide an ACPI video post routine, correct?
For acpi-support scripts double check to have
SAVE_VBE_STATE=false
POST_VIDEO=false
USE_DPMS=false
in /etc/default/acpi-support (location from Debian acpi-support package).
Just to be very sure I did
ln -sf /bin/true /usr/sbin/vbetool
So, many thanks for the good ideas an advice!
If I can be of any other help please call - I am willing to test and try anything suggested (if it does not involve "rm -rf /" :)

If you use vesafb, you probably need "s3_bios,s3_mode" to get the video mode restored.

Just to clarify: what vbetool calls were executed (and when: suspend? resume? both?) and what did they cause?
And did the same happen with swsusp? If yes, which mode was set in /sys/power/disk (platform or shutdown)? Was vbetool also called on swsusp?

This one is only for selecting what video head will be selected during POST at boot (if this video device is the one that will be POSTed at boot of course).
Its not intended for knowning if you have to POST video device at resume.
