Hmmm, very curious... not activated.

My driver release always bring the adater out of ACPI power saving
state.  I suspect that the driver you are using does not do this.
You can check if this is the problem by running 'lspci -v' and verifying
that the eepro100 is in D0 state, not D1, D2 or D3.

Yup, not power up, not plugged in, or just broken.

Ohhh, OK, it must be broken.  This should be impossible, but might
happen with power glitches or internal firmware errors.

With a local machine, a full power cycle (unplug or hard switch, not
soft-power-off) will likely restore operation.
With a remote machine, setting the card to D3 state and then back to D0
state might reset operation.  I use pci-config to do this, but it does
require some expert knowledge to run.

That might be a problem, but the device is too broken to tell.
