Yes.  NetBSD doens't (yet) use PCI native mode on IDE controllers.

Those ie* and sea* and mcd* aren't really "found" ... it's just bogus
debugging output that happened to be enabled in the 1.2* kernels.

Numeric Processor eXtension, I think... the FPU.

That's the PCI-Host bridge...

...and the PCI-ISA bridge.  Don't worry that they're not configured.
(It is possible to attach drivers to them in -current, though.)

That's your VGA card - it has a native mode PCI interface, too.  Don't
worry about it.

...means that the 905 probably didn't work properly in 1.2.1.  *shrug*
I'm told it works well in -current.
