[This is a response to Michael and Andrew's suggestions (thanks) with a
comprehensive debugging session and some observations about the dumpcis
output at the end.]

Yep, that's OK. It seems to be bailing out long before we even play
driver games.

No, I did /not/. Sorry, gdb trace will explain all

Yeah, I agree. Why does it have two blocks of memory?

I agree with you, but it's bailing long before it even decides to play
ed0 games (I think). It's failing in assign_io() which is calling the
memory alloc block check routine with 1024 bytes, which is smaller than
MEMUNIT. urk?
Here are all the details....
I did some more debugging on my ethernet card problem. It looks like
we're failing long before we even start to play driver games.
To recap, here's the data, plus a gdb trace:
# cat /etc/pccard.conf
# Sample PCCARD configuration file
#
# Removing all IRQ conflicts from this file can't be done because of some
# IRQ-selfish PC-cards. So if you want to use some of these cards in
# your machine, you will be forced to modify their IRQ parameters from
# the following list.
#
# IRQ == 0 means "allocate free IRQ from IRQ pool"
# IRQ == 16 means "do not use IRQ (e.g. PIO mode)"
