pci_enable_device() doesn't deal with this; in most PCI setups I've

PCI grew an interrupt enable while you weren't looking:
PCI_COMMAND_INTX_DISABLE
No idea about ARM, but almost all PCI devices made in the past few years
support that bit.
Unless you are using a PCI Express device (maybe PCI-X too?), though,
you cannot count on the bit's presence. It was added in PCI 2.3 I
think. Older PCI devices certainly do not have this standardized bit.
