I had the very problem specified in this bug, with carmic and until recently with and updated lucid. Battery life was just half of the one in Windows, and the laptop got really hot, T0 and T1 reported by acpi were around 55 and 61 C.
I use a lenovo t 500 with an ATI Mobility Radeon 3650. Driver initially was the free Radeon.
Installing and employing the up to date proprietary fglrx
2:8.723.1-0ubuntu4 (lucid updates) 2:8.723.1-0ubuntu3 (lucid) packages
via the dpkg resolved my temperature problem. The temp is now down to
about 41 - 43 C. And battery lifetime is even better than in Windows :-)
Performance is quite similar, though I still have to verify that. First
Impression is nevertheless good.
So maybe it works for some of you guys. The hints here helped me a lot.
