Senao Interrupt Problems

I'd appreciate any help I could get; I'm at the head-scratching phase of 
troubleshooting now.  I have a RedHat 7.2 box and I am running Aaron 
Baer's 2.4.18 HOSTAP kernel.  The card is a Senao 2011CS (the 200mW 
one).  I had this card working using the orinoco_cs driver, but had 
problems with Ad-Hoc mode, so I've turned my focus to HostAP.

What works?

The hostap_cs and related drivers load properly-
[root at gateway log]# lsmod
Module                  Size  Used by    Not tainted
hostap_cs              47500   1
hostap                 65572   0  [hostap_cs]
hostap_crypt            2608   0  [hostap]
pcnet_cs               13248   1
8390                    7468   0  [pcnet_cs]
ds                      7944   2  [hostap_cs pcnet_cs]
i82365                 15172   2
pcmcia_core            48640   0  [hostap_cs pcnet_cs ds i82365]
appletalk              23684   0  (autoclean)
ipx                    19908   0  (autoclean)

My interface comes up, but without a hardware address

[root at gateway root]# ifconfig wlan0
wlan0     Link encap:Ethernet  HWaddr 00:00:00:00:00:00
          inet addr:  Bcast:  Mask:
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          RX bytes:0 (0.0 b)  TX bytes:0 (0.0 b)

Some of the parameters that I set in ifcfg-wlan0 are set such as ESSID.  
iwconfig commands all fail with an error like SIOCSIWESSID: Invalid 
argument.  Obviously there is some critically missing information from 
my iwconfig output.

[root at gateway root]# iwconfig wlan0
Warning : Device wlan0 has been compiled with version 13
of Wireless Extension, while we are using version 11.
Some things may be broken...

Ok, so here are my syslog messges and we see why I don't have a mac address:

By the way dmesg is FULL of stuff like this:
