From 7.1b1's kudzu pcitable: 0x1011 0x0009 "old_tulip" "DEC|DECchip 21140 [FasterNet]" Which causes the board to not get configured at all. The board I have (SMC EtherPower 10/100) works ok with the 2.4 tulip.o, and after fixing pcitable everything works ok.
Duh. Will be fixed in next kudzu build (> 0.88-1)
