The attached patch against 2.6.19-rc6-mm1 fixes some problems in sata_nv with ATAPI devices on controllers running in ADMA mode. Some of the logic in the nv_adma_bmdma_* functions was inverted causing a bunch of warnings and caused those functions not to work properly. Also, when an ATAPI device is connected, we need to use the legacy DMA engine. The code now disables the PCI configuration register bits for ADMA so that this works, and ensures that no ATAPI DMA commands go through until this is done.

Fixes Bugzilla
