There is one obvious bug in src/sys/isa/pnpparse.c, lines 270 and 287
where memory range size treated as byte one, while it is a 256 chunk
long. See 'pnpparse.c.diffs' for patch.
I am not that tough to dig into isa bus sources but somewhere there is a
resource leak. The goal is kldloadable driver for isa/pnp cards.
I have two of it at my test computer (a little bit different).
When I try to kldload driver it shows that first board got the second
resource tuple, while the second board did not got resources due
to lack of free irqs. Sample stub driver with makefile,
verbose dmesg and pnpinfo output provided.
