Adding the following to my kernel config file:

options         PCIC_ISA_ALLOC_IOBASE=0x2a0
options         PCIC_ISA_ALLOC_IOSIZE=0x060
options         PCIC_ISA_INTR_ALLOC_MASK=0xb88f

makes my problem go away for NetBSD-1.5 (and probably also 1.4.3, not
tried). I don't need these on NetBSD-1.4.2. (I need these when I want
to use *two* pcmcia 3com ethernet cards in one laptop). I must say
that I don't understand why this fixes the problem for 1.5 (or which
option really fixes it; I guess the INTR MASK, but...) and why it is
not a problem for 1.4.2. I'll send my experiences in for the NetBSD
laptop FAQ, but if any of you could add some rationale to it that
might be nice). I'm happy again now, but I think it would be nice to
fix this, so that installing NetBSD-1.4.3 and NetBSD-1.5 works for
such machines and cards again. Work around is to use NetBSD-1.4.2
install floppies to install 1.4.3 or 1.5.
