Lowering the freq to 4kHz gets me to where I think you was at this

[root@zoo ~]# perf test -v 21
21: Test object code reading :
--- start ---
Looking at the vmlinux_path (6 entries long)
symsrc__init: cannot get elf header.
Using /lib/modules/3.11.0-rc2+/build/vmlinux for symbols
Parsing event 'cycles'
Reading object code for memory address: 0xffffffff8101ce7d
File is: /lib/modules/3.11.0-rc2+/build/vmlinux
On file address is: 0xffffffff8101ce7d
dso__data_read_offset failed
---- end ----
Test object code reading: FAILED!
[root@zoo ~]#

I.e. we need the follow on patches to fix this issue, right?

I'll merge my changes with your first patch and continue from there.
