Can't check that, but it doesn't look completely wrong :)

There is a problem with using "Triton" in Germany, since some
French company got "Tricon" as a registered trademark, and some
lawyer is suing anybody violating that trademark ...
(That lawyer made a special agreement with Microsoft, BTW, which
allows them to identify the Triton chip-set under Win/95. But a
lot of motherboards used to print Triton in the boot message,
and the dealers had to stop selling them, and to pay $1000 to
$7000i ...)

I'm planning to remove most of the verbose PCI probe messages,
and have a (easily configurable) user-land program know much
more about the different PCI chips, than you'd ever want to
put into the kernel.
Only information that might be useful for debugging in case of
a boot failure should be printed by the probe/attach code, IMHO.
This will remove some 7KB from the kernel binary, and will add
a few tens of KB to the disk space requirements, if in fact lots
more vendors and devices will be known to that code ...
