On an unpatched 2.6.23, I got this:

Feb 11 20:56:52 holly kernel: ptpatch2008: init, (c) 2008 <email address hidden>
Feb 11 20:56:52 holly kernel: ptpatch2008: syscalls c0622540
Feb 11 20:56:52 holly kernel: ptpatch2008: syscall table might be readonly
Feb 11 20:56:52 holly kernel: hooked sys_vmsplice

I ran a quick test of the exploit code, which failed with a "[-] wtf" error,
then a few seconds later the message log filled up with this:
