It is possible that "node/memory interleaving" is enabled in your BIOS.
Go into BIOS and try to see if there is such an option. Disable it and
then retry PLPA to see if NUMA is now working.
It would also be good to know your exact linux release, i.e.
cat /etc/release
uname -a
agreed that this is no more a plpa-related problem, sorry for the noise.

The motherboards are Tyan S2469, a fairly popular and high-end choice
for these processors at the time. The board is at the latest BIOS
level, 1.08, and the vendor has not updated the BIOS since 2004.
The kernel in use is 2.6.22 .
Is there any way to figure out which of the two is the culprit, and work
around this issue?
