Sitting here responding to you on an IBM R40 Thinkpad running Suse 9 Pro.... I'd say - make sure you have a handle on what hardware, i.e. display drivers, connectivity, etc, your laptop has internally.
I haven't had much of a problem, although I confess I still haven't full configured the power management - ACPI.
You might check
www.linux-laptop.org for your specific model to see example configs others have done.
