There are actually at least three ways for connecting an IDE HDD. See
ide-m8xx.c:

---
  8xx_PCCARD uses the 8xx internal PCMCIA interface in combination
             with a PC Card (e.g. ARGOSY portable Hard Disk Adapter),
             ATA PC Card HDDs or ATA PC Flash Cards (example: TQM8xxL
             systems)

  8xx_DIRECT is used for directly connected IDE devices using the 8xx
             internal PCMCIA interface (example: IVMS8 systems)

  EXT_DIRECT is used for IDE devices directly connected to the 8xx
             bus using some glue logic, but _not_ the 8xx internal
             PCMCIA interface (example: IDIF860 systems)

I am probably the only one using EXT_DIRECT. ;-)

Drop me a line if you need schematics.
