Question is on what other archs ns87415 is used because some archs
do not have ide_default_irq() ie. sparc64.

from drivers/ide/Kconfig:
config BLK_DEV_NS87415
        tristate "NS87415 chipset support"
        depends on BLK_DEV_IDEDMA_PCI
        help
          This driver adds detection and support for the NS87415 chip
          (used in SPARC64, among others).

I think sparc64 uses PCI interrupt so this is not a problem.
Are there any other archs using ns87415?
