The only thing is:

Xorg       7982       root  mem       REG                8,3     3443360   
6621153 /usr/lib/dri/r300_dri.so

Xorg itself.

At the moment there are again some glitches - 3 of the 4 applets are "iconless"
but clicking on them still get my interaction - so yes, they are there but not
shown (whatever may cause this - maybe unrelated) - resizing the panel does
bring them back but does not cause erros to appear.
I've got only 2 lines from yesterday to today:

[80165.008860] [drm:r100_cs_packet_parse] *ERROR* Unknown packet type 1 at
13234 !
[80165.008865] [drm:radeon_cs_ioctl] *ERROR* Invalid command stream !

So i am still unable to tell (yet) which program or X usage does cause this.
