Woo hoo! for the first time  in the 2+ years I've owned it I can resume my
T520. Removing VESA from the kernel did the trick!

After resume, X was rather slow for some operations. Not painfully slow,
but noticeably slower than normal. I did nothing to the system but ran
x11perf. After about 2.5 hours it completed. When I resumed use of the
system, it seems to be back to normal. No idea what made it change.

I am running Gnome2, so it is a very heavyweight  system running 9.2-Stable
from last Wednesday (r255013).

I'm delighted to finally have a working resume.  It's been YEARS since I've
had it that works on any of my Thinkpads (600E, T43, T520).
