Not sure I really follow this response... ipath_driver.c has

	case PCI_DEVICE_ID_INFINIPATH_7220:
#ifndef CONFIG_PCI_MSI
		ipath_dbg("CONFIG_PCI_MSI is not enabled, "
			  "using IntX for unit %u\n", dd->ipath_unit);
#endif
		ipath_init_iba7220_funcs(dd);
		break;

so clearly ipath_init_iba7220_funcs() was intended to be built and used
even if CONFIG_PCI_MSI was not defined.  From the code it looks like all
should work fine if PCI_MSI is not set, so I don't know what you mean
about conditional checks.

(BTW since I'm looking at this code, "IntX" should probably be
capitalized as "INTx" to match what the PCI specs say)
