yeah, I don't really understand how the solaris idle page scrubbing
interacts with whatever. scrubbing's a hardware feature for AMD. It
needs to be turned on, but you can do this before or after boot:

There's scrubbing for both DRAM and cache.
Solaris does need to report the errors somehow, and I've not tested
that. This is a problem, but my WAG is that it works or doesn't for
AMD, irrespective of the BIOS. The very old script above worked with
phenom II 910 (new, 45nm) therefore it seems AMD has not changed the
knobs much.
