Nice ... Let me start looking at that soon.

a proper topo map (see the one for Joyent-Compute-Platform-1101 in
illumos). Please do not use third-party utilities for this, especially
binary-only ones like LSI's. Note also that the existing code should

that correctly provide LED control (it's rare to find ones that don't);
We've run across some SMC kit which had this issue. A chipset rev
without a firmware update resulted in some non-operational LEDs.
the separate map is needed only for DA architectures.
If any of that is not working correctly on your systems, we should get
bugs filed and figure out what's wrong.
Cool. Going to start looking at using it.
We've had a few nasty surprises on BIOS revisions on SMC kit, in that
BIOS tables set during POST aren't always what one might expect. Which
leads to some very interesting/painful crashes.
It's critical to validate the firmware versions that you use and force
your vendor to deliver only those versions, regardless of who the vendor
is. As you well know, locking firmware revisions is pretty much the
first and most basic aspect of vendor management one learns. :)
Not just firmware, but chipset/board set revisions as well. We've got
horror stories on non "copy-exact" parts.
Thanks on the pointer to libtopo. Checking it out now.
