 The PR says only:
 >> undefined references inside "le_isa_intredge" and "le_isa_attach"
 
 and I got:

 No idea if they are same or not.  Anyway exact error messages are
 always appreciated, so that other users can also google it.

 if_le_isa.c is pulled by "bicc at isa" line
 via sys/dev/isa/files.isa:
  http://nxr.netbsd.org/xref/src/sys/dev/isa/files.isa?r=1.163#238
 
 and MI am7990 driver (requried by all lance based drivers) is
 pulled by "le at bicc" line via sys/conf/files:
  http://nxr.netbsd.org/xref/src/sys/conf/files?r=1.1082#676
 
 Then enabling bicc without "le* at bicc?" pulls only if_le_isa.c
 and it can't find MI lance functions.

 We can avoid errors wrap most code in if_le_isa.c with
 #if NLE > 0 / #endif etc. but I'm not sure it's worth
 to allow such "bicc without le" settings that would simply say
 "le at bicc is not configured."
 
 >  And what about strange FireWire driver problems?
 
 I can't reproduce any problem, probably due to differnt procedures.
