Ubuntu 5.10 works very well on a wide variety of laptops, including
suspending to RAM.  See https://wiki.ubuntu.com/LaptopTestingTeam for
details  swsusp2 is a very invasive patch which conflicts with more
important changes in our kernel (such as the updated ACPI subsystem).  This
cost is not justified by a performance benefit.  If it is adopted upstream,
we can use it, but currently it does not seem like a good choice.

If Ubuntu doesn't support your laptop properly, don't declare that Ubuntu
doesn't work on laptops; instead help to track down the cause of the
problem.  This is what the Breezy laptop mission was about.

I think the open source driver works correctly, but the one supplied by
nVidia does not.  I don't have an nVidia-based laptop though.
