Here's what lspci shows, first after power up (when only two cards are
recognized) and second after reboot:

Note that, although it appears to see the card at 01:00:0 in both
cases, in the first one it doesn't see it's three individual ports.

Am I correct that that would tend to point towards a power issue as
apposed to anything related to udev?  I'd think so, as it seems like
the underling hardware isn't getting seen properly in the first place.
