Same 8-processor incorrect info on my PIII Dell laptop -
redirecting '/usr/bin/top' stderr gets this:
[asuardi@dolphin linux]$ cat x
fscanf failed on /proc/stat for cpu 1
fscanf failed on /proc/stat for cpu 2
fscanf failed on /proc/stat for cpu 3
fscanf failed on /proc/stat for cpu 4
fscanf failed on /proc/stat for cpu 5
fscanf failed on /proc/stat for cpu 6
fscanf failed on /proc/stat for cpu 7
fscanf failed on /proc/stat for cpu 1
So I'd assume anything touching /proc/cpuinfo is hosed.
