The most weird thing is that, when I _rmmod_ the module, the link leds 
will show a link, _before_ I even re-modprobe it! So somehow the removal 
(or even an unbind via the sysfs interface) "resets" it.

I made the same discovery. According to mii.h bit 0x20 would mean 
"Auto-negotiation complete" and bit 0x04 would mean "Link status".
