I don't know why those bits are set as they are.
I followed your instructions and set ONLY 
    set_ee_media to 1
    set_ee_media_auto" to 1. 
    vortex-diag-media -w
Where vortex-diag-media is the modified vortex-diag program with your changes.

Nope.
The network on that system is in SLOW mode, and mii-diag won't touch the bits.

And that was with the 1.17 driver that USED to just force 10Base-T
when it thought it couln't talk to the MII's.  My theory is that the
combination of old EEPROM values, plus the couple set by the
patched vortex-diag put the chip in a state where:
	The 3c59x driver thought the MII was alive and well.
	But where it could not, in fact, speak to the MII properly.

Having mastered the lore of getting the crappy GX150 floppy actually to
work, I've used the DOS utility to set the EEPROM, and I've included the
vortex-diag output of the bits as they differ from "athenaphoba after replug".

Suggested next steps:

Tell me what bits need to change in the vortex-diag EEPROM diddling
patch to make things happy.  As shown below.

(It is my hope that the before, after, after-replug, and the DOS outputs
give you a complete picture of bad and good EEPROM values.)

P.S.  Thank you VERY much for taking so much time to help sort this out!
