No.  It just means that no other module depends on x86_pkg_temp_thermal.

b43 is Broadcom 43xx wireless support
*80211 are for wireless 802.11 and not needed at this point

RF switch subsystem support -- not needed now

Looking at the help in the kernel for CONFIG_R8169:

Selects: FW_LOADER [=y] && CRC32 [=y] && MII [=y]

so mii is probably selected automatically.  The question the above line 
gives me is whether there is a firmware blob for this card.
