I set that on kernel command line at first and removed "options 
radeon agpmode=4" from my /etc/modprobe.d/99-local.conf.

That went well for the first resume cycle. The second resume just 
shortly after the first failed without any possibility to record 
anything like logs (VT switching impossible, hard lock).

Then I went to /etc/X11/xorg.conf setting the # in front of:
#	Option		"BusType"		"AGP"
#	Option		"AGPMode"		"4"

That now worked for 4 subsequent hibernate/resume cycles with 
ascending memory usage. I can't see any performance impact.

Any clues?
Yes, the logs have many diffs now!!!
