I have figured a way to get wifi to work. I discovered that the acer_wmi module loads by default and I had originally blacklisted it because it added "acer wireless" as a device. In order to get this to work I had to remove it from the blacklist. Below are the steps I followed.
1. Login in (assuming acer wireless module gets loaded) and select Enable Wireless from network applet
2. Enable to wireless on the ideapad (Fn-F5)
3. Now, run sudo rmmod acer_wmi
Wifi connects immediately
Adding acer_wmi to the blacklist causes Natty to freeze on the Ubuntu loading splash screen. If you manage to get in this situation you have to get into initramfs by adding break=bottom to the kernel boot line. After you've remounted /root to make it writable you can restore the blacklist file if you backed it up. If you didn't back up the file first you'll need to run sed on the blacklist.conf and fix the line.
