Windows 10 drivers list them, they do show up on lspci and I'll quote
from Atom datasheet.
"This register is unique in Function 1 (the Function 0 DID is
separate). This difference in Device ID is necessary for allowing
distinct Plug and Play enumeration of function 1 when both function 0
and function 1 have the same class code."
Whatever this means.
