No, this particular problem is caused by the fact that the CPU
cores hang off of pseudo-busses which group them together in the
OFW device tree of these machines instead of directly from the

Generally support for additional sun4u models is added as such
hardware becomes available and time permits. As for UltraSPARC
IV and IV+ based systems support for these should be already
covered by the changes necessary for V1280 I have in my local
tree, the workarounds needed for several errata of these CPUs
are still missing though.
Could you provide a OFW device tree dump (`prtconf -Ppv` under
Solaris) of that machine?
