For me, sis900 and r8169 stand out; if you look at the data in the
table above, both of these are an order of magnitude more frequent than
the rest of the pack.

via-rhine + via_rhine = 438: it does not look too good either.

Is there an (ideally automated) way to retrieve more information ?

The r8169 driver handles three different chipsets and a plethora of
phys. The "XID" line printed by the driver could hint at some specific
PHY for instance.
