UML 2.6.26 and an older libc:
% ls -l /lib/libc.so.6
lrwxrwxrwx 1 root root 11 Jun 2 2007 /lib/libc.so.6 -> libc-2.5.so
Looking through libc at
http://www.google.com/codesearch?hl=en&q=file:\.c%24+\"/stat\"+package:http://su-se.lunar-linux.org/lunar/mirrors/glibc-2.3.3-cvs-20040708.tar.bz2+show:m1O9RV1wlw4:qbkros5194A:MbxD3_8dUHU&sa=N&cd=1&ct=rc&cs_p=http://su-se.lunar-linux.org/lunar/mirrors/glibc-2.3.3-cvs-20040708.tar.bz2&cs_f=glibc-2.3.3-cvs-20040708/sysdeps/unix/sysv/linux/getsysstats.c
I see it counting cpu<n> lines in /proc/stat, which is what I'm
seeing. It will also look at /proc/cpuinfo. Can you strace your
version and see if it's looking there at all?
