I don't think we are anywhere near removing ISA support (probably
not before removing EISA, which in turn is required for some platforms),
but that was what I implied: No point removing NE2000 support as long as
there are platforms or bus types using that driver (Q40, Atari, TX49xx),
and even the ISA version of NE2000 may outlive other CONFIG_ISA
itself because it is a typical emulation target.

Same here, I specifically mean the drivers that are /only/ used for ISA
here: CONFIG_LANCE and CONFIG_NI65, not the various other lance
