More news.
I messed with the BIOS on my computer, and instead of having IRQ11
hardcoded for all of the PCI interrupts, I chose 'Auto-Select IRQ' for
the 4 different settings. With this change in place, all of my PCMCIA
cards are now recognized (pccardc dumpcis now works) with the old
(Aug. 5th) codebase. Now using, the previous kernel, my network card
(D-Link DE660) and serial cards both work fine if I hard-code the
interrupts to use in /etc/pccard.conf. Otherwise
===================/etc/pccard.conf===================
irq 3 9 10 15
# D-Link DE-660 NE2000 clone
card "D-Link" "DE-660"
config auto "ed0" 9 0x10
# config auto "ed0" ? 0x10
insert /etc/pccard_ether $device start
remove /etc/pccard_ether $device stop
# USR Sportster 33.6
card "U.S. Robotics" "SP1336"
config auto "sio" 3
# config auto "sio" ?
===================/etc/pccard.conf===================
Otherwise, if I have it auto-select an IRQ (for either card), it fails
to find a usable interrupt, even though irqs 3 & 9 are available per the
top of the file. This is not necessarily a bug, but a regression.
[ Update, ignore this. Auto-select works fine once I reverted the pccardd
change that accompanied the new codebase.

One bad thing that's part of the old code is that if I configure the
network card and use it, I can't pop it out w/out first doing an
'ifconfig ed1 delete', because it'll hang FreeBSD. (FWIW, I could
hot-swap it in FreeBSD 2.2, so this is a regression.)
So, in summary, something in the new pcic/PCI routing code is definitely
screwing up things so they don't work right, where the old code works
fine, modulo the hot-swap issue.
The code I'm using is from Aug. 5, and it works *great* if I use a
pccardd that matches the code.
The new code was from a couple of days ago, and it hangs at boot-time if
any cards are inserted, or as soon as a card is inserted (using a
pccardd from the same vintage doesn't seem to make any difference).
One final note, this is the first time I've actually used the
pcic/pccard code since I quit maintaining it oh so many years ago.
Congratulations go to Warner for keeping things not only working, but
working even better than before, considering all the various and sundry
infrastructure changes that have gone on beneath it (newbus, etc..).
