Help needed: SanDisk Connect Plus with hostap_cs on Sharp Zaurus

[Dr. H. Nikolaus Schaller]

Dear all,
I could make the card being recognized and hostap_cs being loaded. But 
now, I get the following dmesg:

hostap_crypt: registered algorithm 'NULL'
hostap_cs: 0.1.2 - 2003-11-02 (Jouni Malinen <jkmaline at cc.hut.fi>)

In other occasions I get a message like hda: interrupt lost. So there 
seems to be something goring wrong with the interrupts.

Looking at /proc/interrrupts shows that IRQ 35 is registered for 
hostap_cs (for WLAN) and ide_cs (for the memory part of the card)

Here is my conf file:

#
# configure to recognize SanDisk ConnectPlus card
#

device "hostap_cs"
    class "network" module "hostap", "hostap_cs", "hostap_crypt", 
"hostap_crypt_wep"

card "SanDisk ConnectPlus 128M"
         manfid 0xd601, 0x0101
         bind "hostap_cs" to 0
         bind "ide_cs" to 1

# somehow needs to fix IRQ

module "hostap_cs" opts "dev_template=eth%d"

# module "hostap_cs" opts "channel=6 iw_mode=3 essid='<the essid of 
your network>' ignore_cis_vcc=0"

Any hints are greatly appreciated
