I have a T43 2686-DGU and all of my problems where solved with the ACPI fix 2 months ago (I think). My machine suspends to RAM and resumes correctly 100% of the time. As a side note suspend also works 100% with both the 'ati' driver and 'fglrx'. fglrx had given me grief in the past. Also, the old SATA resume bug is gone.

Around the same time as the ACPI update, I was mucking with /etc/default/ acpi-support so here is my file:
Hopefully this will help someone get their machine working. I feel your pain.
