I tried this on x86_64 - and immediately ran into a problem with the
debuginfo. Observe:
jistone@jistone-xen64 /usr/lib/debug/lib/modules
$ ll */vmlinux
-rwxr-xr-x 1 root root 42M Mar 14 13:49 2.6.15-1.2054_FC5kdump/vmlinux
-rwxr-xr-x 1 root root 44M Mar 14 13:00 2.6.15-1.2054_FC5/vmlinux
-rwxr-xr-x 1 root root 7.2M Mar 14 13:15 2.6.15-1.2054_FC5xen0/vmlinux

The sizes for the xen* kernels are way too small to contain all of the
debug information. And indeed, when I run stap, I'm told "cannot find
module kernel debuginfo: No DWARF information found".
