You can pass --enable-debug to the configure script in order to enable
debug symbols (and don't strip programs/libs). For the kernel and
modules,
define CONFIG_XENO_OPT_DEBUG and CONFIG_DEBUG_KERNEL/CONFIG_DEBUG_INFO
to have symbols and all. OProfile is only able to look up virtual
address
when debug symbols are present in file. You may have to pass the 
--vmlinux option to opcontrol. Compiling Xenomai like suggested by Jan
will make your life easier, and will bring you an extra mini speedup
if you're in that kind of business.
