    Nope. But I don't think that I can configure it anyway. The thing is
    that this particular setup doesn't use ULi's i8259 PIC (it is disabled by
    one of PCI quirks), and IDE interrupt is a sideband PCI-E interrupt (also
    configured by the PCI quirk). So IDE interrupt is "directly" connected to
    OpenPIC interrupt line (through the SOC PCI-E controller, of course).

    If that ULi bridge (M1575) provides some other means of configuring, I
    could try it... with the specifications.
