So, I tested 2.4.7pre6 with eepro100 build as a module and the problem (network broken after ifconfig down/up cycle) persists.
"lspci -vvxxx" output between the good "D0" state and the bad one is identical. Output for the D2 state just differs in the "e0:" line, which seems to be OK.

I will see that I can make the "eepro-diag" working.
