Very confusing :-( 
I see in modinfo, what makes me think it uses rtl8192cfw:
firmware: rtlwifi/rtl8192cfwU_B.bin
firmware: rtlwifi/rtl8192cfwU.bin
firmware: rtlwifi/rtl8192cfw.bin

but: description: Realtek 8192C/8188C 802.11n PCI wireless

With a clean install of Ubuntu 12.04, upgraded to kernel 3.2.0-54,
wireless does not work: error in dmesg "Failed to request firmware!"

There are a quite a lot of differences with your output,  you are right
that the problem lies at ubuntu packaging. While testing this, I noticed
that rtl8192cfwU_B.bin and rtl8192cfwU.bin where missing and requested
by the driver. Copying those in from the Realtek website makes the wifi
work again :-).

missing in the Ubuntu installation:
rtl8188efw  
rtl8188eufw
rtl8192cfwU_B
rtl8192cfwU
rtl8192cufw_A
rtl8192cufw_B
rtl8192cufw_TMSC

different:
rtl8192defw
rtl8192sefw
rtl8712u

the same:
rtl8192cfw
rtl8192cufw
rtl8723fw_B
rtl8723fw
