Ok Here is a quick fix for wifi with 5.01H apps to sd:

Download wlan.ko
Copy it to sd, unmount after copy
Get terminal emulator from the market
type su
Then type:
Code:
mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system
then:
Code:
rm /system/lib/modules/wlan.ko
cd /sdcard
cat wlan.ko >/system/lib/modules/wlan.ko
reboot phone and wifi works

In hakuro's rush he just added the wrong wlan.ko, he had a busy day and did allot for us, its all good now
