Let's look at the rest of the situation surrounding HAVE_IDE first.
It's something of a mess:

avr32, m68knommu, ppc, s390 and v850 do not have asm/ide.h

avr32, m68knommu, ppc, v850 all set HAVE_IDE, arch/s390/Kconfig contains
no reference.

avr32 supports PATA (which is IDE).

Everything else provides an asm/ide.h and sets HAVE_IDE.

So:

Q1. Do avr32, m68knommu, ppc, v850 have IDE support or do they not?
Q2. Should avr32, m68knommu, ppc, v850 supply an asm/ide.h header?
Q3. Is it worth supporting HAVE_IDE for all kernel architectures when
    its just one (s390) which supports neither IDE nor ATA - or would
    something more generic covering both be appropriate.
