[fakePATCH] non-PCI ide

A moment ago I compiled 2.5.8 for a non-PCI 486.
Below a diff that makes it compile (and work),
modulo other patches that have been posted already.

Of course this is not a suggestion to put in those #ifdef's,
this is just to point out that pci_dev is undefined when
CONFIG_BLK_DEV_IDEPCI is not set. You might consider putting
something like

  #ifdef CONFIG_BLK_DEV_IDEPCI
  #define PCI_DEV(drive) (drive->channel->pci_dev)
  #else
  #define PCI_DEV(drive) (NULL)
  #endif

in some header file. Or, alternatively, just always define
the field pci_dev in this struct, wasting 4 bytes and avoiding
the #ifdef's altogether. In case you do that, soon the entire
CONFIG_BLK_DEV_IDEPCI becomes superfluous.
