Doh!  Of course!  I guess I should have known that.  Although I was
expecting something in Opie.  But iwconfig is fine, too.

Thanks for your reply, Tom.  It seems that mine loads the orinoco driver by
default too, but I also see hostap modules in the kernel after inserting the
card:

Module                  Size  Used by
hostap_cs              56596  0
hostap                112804  1 hostap_cs
ieee80211_crypt         5056  1 hostap
orinoco_cs             14884  2
orinoco                40180  1 orinoco_cs
hermes                  6336  2 orinoco_cs,orinoco

when I do hostap_diag wlan0, I get this:

ioctl[PRISM2_IOCTL_HOSTAPD]: No such device
Could not communicate with the kernel driver.

How do I force the use of hostap when orinoco loads by default?

Great!  Thanks for all the good info, Tom.  I just may try making my Zaurus
into an access point repeater too!
