One note on these results:
=============
This one has utrace/uprobes support.
Host: Linux trillian.ltc.austin.ibm.com 2.6.32-131.0.15.el6.ppc64 #1
SMP Tue May 10 15:44:09 EDT 2011 ppc64 ppc64 ppc64 GNU/Linux
Snapshot: 430f532
GCC: 4.4.5 [gcc (GCC) 4.4.5 20110214 (Red Hat 4.4.5-6)]
... stuff deleted ...
UNTESTED: 32-bit access nd_syscall
UNTESTED: 32-bit acct nd_syscall
UNTESTED: 32-bit alarm nd_syscall
...
==============
I'd guess those "UNTESTED 32-bit" results are because the machine
doesn't have a 32-bit development environment installed. Since this
appears to be a RHEL6 box, the following command should fix that:
# yum install glibc.ppc libgcc.ppc glibc-devel.ppc
