[just sent this to Andrew and Linus]
Includes the following major changes:
* much improved exception handling infrastructure, which in turn
makes many other things possible, and/or fixes some hard-to-fix
categories of bugs.
* IRQ-driven PIO, rather then polling from kernel thread, by default
* tagged command queueing ("NCQ")
* device hotplug (all SATA is natively hotplug-capable)
* continued PATA improvements from Alan
* new controller support, mostly via new PCI IDs
* (NOTE NOTE) adds more nvidia support to drivers/ide, in addition to libata
