This is ugly, stupid, and wrong.  I don't know why it works.  It works.

In usb/:
if_aue.c:
{{ USB_VENDOR_ACCTON,         USB_PRODUCT_ACCTON_SS1001},       PII },
usbdevs:
product ACCTON SS1001           0x5046  SpeedStream Ethernet Adapter

In mii/:
miidevs:
model ALTIMA NEWBIE             0x0001 ACNEW 10/100 media interface
acphy.c:
        { MII_OUI_ALTIMA,               MII_MODEL_ALTIMA_NEWBIE,
	  MII_STR_ALTIMA_NEWBIE },

Make sure acphy is in your kernel, and this seems to work.

No, I don't believe that the official model name for this PHY is "newbie".
I don't know what it's called, I have no documentation, and I don't have
any clue what to make of it.  But it works.
