Yep, proper WPA AP:
~$ wpa_supplicant -Dwext -c/etc/wpa_supplicant.conf -ieth0
ioctl[SIOCSIWENCODEEXT]: Operation not supported
ioctl[SIOCSIWENCODEEXT]: Operation not supported

and the DHCP offer:

adding dns 192.168.0.1
But I am a few metres away from the AP, maybe it helps.

Ah that can be about your AP perhaps? The powersaving thing relies on a
rendezvous at beacon times to pick up packets (and the client WLAN
powers down for ~100ms inbetween), maybe the problem can come from the
AP side. Mine is a Belkin F5D7230-4.

Maybe it is not the AP.
I did already a 50MB transfer to time it initially:

No problem... I did not see the spinlock BUG() yet since updating
everything, so that is encouraging, but I didn't reboot many times yet.
Peripheral clock is 50MHz, yes:
[ 0.000000] S3C244X: core 400.000 MHz, memory 100.000 MHz, peripheral
50.000 MHz
One other minor thing, maybe it's not actually your problem either, but
the iwconfig data about signal strength is either unscaled or broken.

PS Actually, a couple of other things... can we expect Monitor Mode and
raw injection? I realize we are at the mercy of the firmware there.
