I have this on my Sony VAIO.  Alan Cox said that it was the ACPI version
of a bug he recently squashed in the main kernel.  Basically nothing
should try to assign interrupts to devices which use Legacy IRQs (ie the
IDE controller in our case).

Hopefully the ACPI guys can work out some way of detecting if the device
is legacy or not and just ignore it if it is.  They didn't respond to
Alan Cox's message to acknowledge it.

It's a warning though, the IDE controller gets IRQ 14 and 15 anyway and
all seems to be ok.
