I'll try to find a work machine to fetch that from (it's drunk the "we
want to ram HTTPS down everyone's throat" koolaid, so I can't fetch the
content from my own machines).  Thank you!

I'm hesitant to do that because I don't know what it could do to it to
be powered up without the crystal present.  I don't see anything else I
recognize as a crystal, but (a) there may be one lurking and (b) some
electronics can self-fry if powered but unclocked.

I may take an ohmmeter to it though, to try to find any pins which are
directly connected to PCI power/ground pins.
