This is reporting the EEPROM media setting, which should always be 0x0800.

Are you using "insmod tulip options=12"?

The default setting is '0', 10baseT-autosense.  It will still switch to
10base2/AUI if link beat is lost.  You must use '12', "10baseT(forced)" to
prevent the media type from being switched on loss of link beat.
