Finally configured my pcmcia wireless card (Asus wl100) :
apt-src import kernel --location=/devel/kernel/2.4/linux/ --version=2.4.24
cd /devel/kernel/2.4/linux/
apt-src --installdebs install linux-wlan-ng
Had to fix /etc/pcmcia/config.opts, since kernel oopses if you use th x86 standard ports:
include port 0x100-0x4ff, port 0x1000-0x17ff
include memory 0x80000000-0x80ffffff
exclude irq 1
exclude irq 2
exclude irq 19
exclude irq 20
exclude irq 25
exclude irq 26
exclude irq 27
exclude irq 28
exclude irq 41
exclude irq 42
exclude irq 47
exclude irq 55
exclude irq 51
Relevant /etc/network/interfaces:
auto wlan0
iface wlan0 inet dhcp
wireless_mode managed
#wireless_mode ad_hoc
#wireless_channel 1
#wireless_essit ''
