A new, reworked version of ISAPNP hardware detection script is attached
as a patch to the hotplug package.
This release is based entirely on Simone Gotti's approach. Simone
Gotti's approach is preferred because it provides proper blacklist
support. However, it is unsuitable for Debian because this script uses
stuff from /usr/bin.
The artificial split into isapnp.rc and isapnp.agent has been removed.
Support for 2.4 kernels has been removed.
Two bugs reported against hotplug-isapnp-0.2.1 by Simone Gotti have been
fixed:
1) bashism resulting in messages like "[: ==: binary operator expected"
2) wrong behaviour with empty /sys/bus/pnp/devices directory
As usual, this script will work only if the kernel has been compiled
with CONFIG_ISAPNP=y and CONFIG_PNPBIOS=y.

I'm experimenting with bootable CDs, working up hardware detection for
essentially any kind of system Linux supports. I recently stumbled onto a bug
(or perhaps "omission" is more accurate) in the pnp.rc script.
The problem is this: I found a system that uses an ISA pnp network card. The
pnp.rc script doesn't load a driver for it because the card's identifier
string (something like @@@5e90 -- I made up the numbers, but the beginning @
symbols are included in the card's id string).
The card includes a second, generic identifier string in the form PNP80d6.
This generic identifier does resolve to a valid driver module.
I'm putting together a modification of your pnp.rc script that uses the
generic identifier if the initial one doesn't turn up a driver. Would you
rather do this yourself?
Regards;
Jonathan

Could you please execute the following commands:
cd /tmp
cp -a /sys .
tar zcf sys.tar.gz sys
and mail the resulting sys.tar.gz file to me (off-list)?
