Title:
  [Sony VAIO VPCEL2S1E] Ubuntu loads acer-wmi on WiFi not working

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  I am trying the Ubuntu Daily ISO (20/2/2012) and I notice that the WiFi is not working.
  Upon inspection, rfkill reports:

  0: acer-wireless: Wireless LAN
   Soft blocked: yes
   Hard blocked: no
  1: sony-wifi: Wireless LAN
   Soft blocked: no
   Hard blocked: no
  2: sony-bluetooth: Bluetooth
   Soft blocked: no
   Hard blocked: no
  3: hci0: Bluetooth
   Soft blocked: no
   Hard blocked: no
  4: phy0: Wireless LAN
   Soft blocked: no
   Hard blocked: no

  WORKAROUND: So, acer-wmi.ko was loaded though it was not required for this Sony laptop.
  Therefore, I run:
  rmmod acer-wmi

  and instantly the WiFi worked.

  Is it possible to blacklist acer-wmi for this Sony laptop (or a range
  of Sony laptops)?
