The kernel on 12.04 doesn't currently support Wacom Intuos5 tablets. Adding the following patches from the mainline kernel would fix that:

- these two are not strictly needed, but make the rest apply cleanly
8b4a0c1fe3b03c0cfe829413481d69c2e6fd844c Input: wacom - use BTN_TOOL_FINGER to indicate touch device type
31175a8348af76aea2f557857c90467d13632dc3 Input: wacom - use switch statement for wacom_tpc_irq()

- these patches lay the groundwork for Intuos5 (from v3.4)
3aac0ef10bf5c76ba4262cfd9b044a6c067d5aae Input: wacom - isolate input registration
d3825d51c3eddb8a3c7d1281f27181aff6db19b8 Input: wacom - wireless monitor framework
16bf288c4be67b68c3fcb6561ff145702cb7bd22 Input: wacom - create inputs when wireless connect
a1d552cc15b0be9124ccba593f99f59c4ec1e153 Input: wacom - wireless battery status
f182394033d639679264d61e6dca62761e659ff7 Input: wacom - check for allocation failure in probe()

- and finally the actual Intuos5 support (from v3.5-rc1)
9fee619505bdb202c9f54b58ec996884160cdbf2 Input: wacom - add basic Intuos5 support
f860e581fd473250c6dcbd3e13d576b6197e4694 Input: wacom - add Intuos5 Touch Ring/ExpressKey support
9b5b95dd516a13d53ecf9217672d2116f05097bc Input: wacom - add Intuos5 Touch Ring LED support
ae584ca473289377dd7fd8c61439db4bfab5489a Input: wacom - add Intuos5 multitouch sensor support

I've tested the patches on top of 3.2-25.40 and they work fine, and my Intuos4 continues to work as well. The Intuos5 support patches missed the 3.4 merge window due to a human error, so they're actually a bit older and have seen more testing than the kernel version would suggest (linuxwacom provides a kernel driver "snapshot" for users to install a bit like our dkms packages are).

The quantal kernel is missing support as well, but 3.5-rc1 is already being worked on, so best to just concentrate on precise here.
