this broke the ne driver:

CONFIG_PNP is not set

with drivers/pcmcia/i82365.c as an example I could get this to build (see 
patch below), as noted in Documentation/pnp.txt this is not the correct fix, 
but it works for now.

with patch below, kernel builds, boots and it servives a simple stresstest 
(the bandwidth program in
