DISABLE_PCI_IDE works by arranging for buggy code in wdprobe() to not be run. It doesn't actually disable PCI IDE, since simiilar but non-buggy code in wdgetctlr() is still run. It disables buggy support for (Promise only?) IDE interfaces with more than 4 devices. PCI IDE is disabled by not enabling it in the wdc flags. ALI_V has no effect except to obfuscate the code.
