Prism2 driver with Addtron AWP-100 runs out of tuples

I have a Linux 2.4.14 (based on Debian Woody), with non-kernel pcmcia 3.1.31, on a Compaq 5250.
Building & installing the prism2 went ok, and the driver is correctly detected in the insertion phase.
However, after then, it all goes rapidly pear-shaped. I get this:

Jan 30 17:08:14 localhost cardmgr[168]: socket 1: Addtron AWP-100 11Mbps WLAN Card
Jan 30 17:08:15 localhost cardmgr[168]: executing: 'modprobe prism2' Jan 30 17:08:15 localhost kernel: prism2: prism2.c 0.0.0 2002-01-03 (SSH Communications Security Corp, Jouni Malinen) Jan 30 17:08:15 localhost kernel: prism2: (c) SSH Communications Security Corp <jkm_at_ssh.com>

Resource temporarily unavailable
Jan 30 17:08:16 localhost kernel: prism2_detach Jan 30 17:08:16 localhost kernel: prism2: link->dev == NULL: do not unregister netdevice

So I debugged slightly (I'm not really technical) and inserted more debug traces, and got this: 

Jan 31 02:10:01 localhost kernel: Checking CFTABLE_ENTRY 0x01 (default 0x01)
Jan 31 02:10:01 localhost kernel: cfg vcc ignored going to next entry
Jan 31 02:10:01 localhost kernel:  <7>vcc present= 119 conf vcc= 32
vccparam= 330000++ ignore=0

(after inserting the following line in prism2

PDEBUG(DEBUG_EXTRA, "vcc present= %d conf vcc= %X vccparam= %d++ ignore=%d\n ",cfg->vcc.present, conf.Vcc, cfg->vcc.param[CISTPL_POWER_VNOM], ignore_cis_vcc);

I don't understand. From the code, I see why it's doing what it does - abandon the CIS entry, and look for the next, but where did 3.2V come from?
(and is it really there or have I just made an amusing error in my
blundering attempts to debug).

Has anybody else seen this?
What can I do? Can I override the config putting a cis dump with different values in the pcmcia package?

Here is the CIS:
