I've got hostap and hostap_pci in /etc/modules.
me@~$ dmesg
...
ieee80211_crypt: registered algorithm 'NULL'
hostap_pci: 0.4.4-kernel (Jouni Malinen <jkmaline at cc.hut.fi>)

But NB, there's NO entry "hostap_pci: Registered netdevice ..." of
any sort. So maybe it didn't find the hardware.

Nothing is changed by
root@~#modprobe hostap hostap_pci
It remains
root@~$ lsmod
...
hostap_pci             48912  0
hostap                 99140  1 hostap_pci
ieee80211_crypt         5280  1 hostap

root@~# ifconfig wlan0 up
wlan0: ERROR while getting interface flags: No such device

root@~# ifconfig -a

lo        Link encap:Local Loopback

...

There are no new messages in /var/log/syslog, messages, or kern.log
after these operations.

Actually, I've tried dozens and dozens of ways of getting wlan0 to
recognize one or another access point, including four or five versions
of /etc/network/interfaces, following one or another of the files in
/usr/share/doc/(various). It would take pages and pages to describe it all.

iwconfig wlan0 didn't *stop* working. Before and after loading
drivers, on clean reboot as well, it is constant:
root@~# iwconfig wlan0
wlan0     No such device.

me@~$ dpkg -l 'hostap*' pcmciautils wireless-utils

ii  wireless-tools 28-1           Tools for manipulating Linux Wireless Exten

The "iF" regarding hostapd is, I think, because it has consistently
failed to set up with three versions of hostapd: 1%3a0.3.7-2, 0.5.0-1
and 0.5.3-1. (apt -f install fails to get any of them fully installed.)

root@~# uname -a
Linux lapdog 2.6.16-lapdog #1 Sun Jul 2 17:04:48 EDT 2006 i686 GNU/Linux

I get the same (lack of) results with an earlier version 2.6.16
as well as the version of 2.6.15 for which hostap-modules last
built. The .config file for all three kernels reads the same:
root@~# cat /boot/config-2.6.16-lapdog | grep -Ein hostap
963:CONFIG_HOSTAP=m
964:CONFIG_HOSTAP_FIRMWARE=y
965:CONFIG_HOSTAP_FIRMWARE_NVRAM=y
966:CONFIG_HOSTAP_PLX=m
967:CONFIG_HOSTAP_PCI=m
968:CONFIG_HOSTAP_CS=m

root@~# pccardctl ident

Socket 1:

  manfid: 0x0156, 0x0002
  function: 6 (network)

Incidently, the card shows up only once in dmesg:
...
pcmcia: registering new device pcmcia1.0
...

Agreed, but it doesn't.

I hestitate to mention it, but the card works find under Windows XP
Pro.

Pavel, again let me offer thanks for your help.
