I hope so!

I've sent a query to some of the IBM'ers I know in case
they can shed some light.

On our Power6 box with SLES10 those topology directories
are empty.. :-(

# ls /sys/devices/system/cpu/cpu0/topology/
# uname -r
2.6.16.60-0.54.5-ppc64
#

That said 1.0.2 and 1.1a1r2387 still appears to get mostly
the right layout (it misses the fact that it's SMT).

Machine (31GB)
  NUMANode #0 (phys=0 15GB)
    PU #0 (phys=0)
    PU #1 (phys=1)
    PU #2 (phys=2)
    PU #3 (phys=3)
  NUMANode #1 (phys=1 16GB)
    PU #4 (phys=4)
    PU #5 (phys=5)
    PU #6 (phys=6)
    PU #7 (phys=7)

cheers,
Chris
