Vivek, There is IBS support in perfmon since 2.6.24. If you download the latest libpfm, you will find an example (examples/x86) showing how to get access to it using the perfmon interface.
If you pull libpfm from CVS, there is a man page (man libpfm_amd64) that describes the IBS support for libpfm, If you need more information, post on this list.
