There are also problems with the powermanagement (at least for me). I use a HP nx7400 notebook with Intel i945gm chipset and a Core 2 Duo (T5600) CPU.
Specific problem: The speedstep_centrino module returns "No such device". The acpi_cqufreq module does load, but doesn't provide any frequency scale ability. -- Backport Intel 965 Express chipset support from 2.6.18 https://launchpad.net/bugs/61342 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
