I ran into a problem while using compat-wireless to compile new wl1251 driver for N900

Here is what I've done:
1. follow this N900 kernel compile tutorial to recompile the 2.6.28-omap1 for N900 with "CONFIG_CFG80211=m" in .config, which is required by compat-wireless
http://natisbad.org/N900/n900-custom-kernel.html
Code:
scp mac80211.ko cfg80211.ko wl12xx.ko  nokia:/lib/modules/current
sudo flasher-3.5 -k arch/arm/boot/zImage -f -R
new kernel works great, and phone boot normally with wifi on

2. download lastest stable compat-wireless v3.0-rc4
Code:
./script/driver-select wl1251
ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- make KLIB=/home/cndn1/kernel-2.6.28 KLIB_BUILD=/home/cndn1/kernel-2.6.28
I got 7 modules seems necessary:
compat, compat_firmware_class, rfkill_backport,
cfg80211, mac80211, wl1251, wl1251_spi

then copy the compat_firmware rules:
Code:
ssh nokia
mkdir -p /lib/udev/ /lib/udev/rules.d/
exit
scp udev/compat_firmware.sh nokia:/lib/udev/
scp udev/50-compat_firmware.rules nokia:/lib/udev/rules.d
unload old cfg80211, mac80211 and load new mod with:
Code:
rmmod wl12xx 2>/dev/null
rmmod mac80211 2>/dev/null
rmmod cfg80211 2>/dev/null
insmod compat_firmware_class.ko
insmod compat.ko
insmod rfkill_backport.ko
insmod cfg80211.ko
insmod mac80211.ko
insmod wl1251.ko
insmod wl1251_spi.ko
lsmod shows these modules are loaded correctly, but dmesg only shows "cfg80211: Calling CRDA to update world regulatory domain", no info about wl1251, although I enable DEBUG_ALL in wl1251.h

And the wifi doesn't show up, even if I restart network
ifconfig only shows lo and phonet0


I've read a thread with a guy with similar problem, a lot of discussion but it seems not solved though
compat wireless N900 problem

Anyone worked on compat-wireless for N900?
Any help is appreciated!
