Yes, that seems the correct test to run.

I'm still trying to understand what causes the "1000baseT/Full" to show 
up or not show up for "Advertised link modes"/ 10baseT/Half 10baseT/Full.

My understanding is that during auto-neg each side advertises it's 
highest capability and the 2 link partners negotiate down to a common 
speed/duplex capability.

Also, auto-neg on the link is exchanged when:
1. Link is initially connected
2. Device at either end of the link is powered up
3. Device is reset or initialized
4. Renegotiation request is made

Which means the testing you've has forced auto-negotiation to reoccur. 
Which leads me to believe that it's not strictly a auto-neg problem.

I think we really need to understand the missing Gigabit link mode 
advertisement. Why would the NIC not advertise it sometimes...?
