I'm having trouble reconciling this with the graphics driver.

a) you claim it happens with fglrx as well, there is nothing shared between
them
(so it can't be a common gpu bug)

b) nothing is leaking according to that debug info in anywhere obvious.

One last test would be unload the gpu stack to see what happens

got to runlevel 3 or anywhere X isn't rnunig
echo 0 > /sys/class/vtconsole/vtcon1/bind
rmmod radeon ttm drm_kms_helper drm

see if memory is still gone.

maybe you can watch /proc/slabinfo to see where the memory might be going. It
might also just be page cache from the pdf loading,

does echo 3 > /proc/sys/vm/drop_caches help?
