Here's a data point for you:

I experienced several lockups with my system, a T60p, until I disabled
hdapsd.  The lockups occurred using linux 2.6.16 with then-current
suspend2, tp_smapi, and hdaps-protect patches.  The machine has a SATA
drive and was using the AHCI driver.

I'm currently using 2.6.17 but haven't re-enabled hdapsd, so I don't
know if the situation has improved.
