Maybe this is better?

CONFIG_IDE_TASKFILE_IO
This option enables a new standardized data-transport driver. It replaces
code currently in each chipset/host driver. This should help reduce
bugs and allow better data protection. This new code also packetizes
requests to enable rapid performance and reduce system latency. It also uses
structures so MMIO hardware can be used in second generation Ultra133 and
Serial ATA chipsets.

Since this a a major reworking of current code, this will live along side
current drivers for now. If this doesn't work on your arch yell.

If you want to test this new driver (and have backups), say Y here.
