Assuming your hardware is sane another approach might be to force
drive->unmask = 1. That will mean that PIO mode is running with
interrupts enabled which should avoid the problem.

Add a .fixup handler to your driver (assuming you are using a recent
2.6.x) and in the handler do something like this:

+void ide_unmask_interrupts(ide_hwif_t *hwif)
+{
+       int i;
+       for (i = 0; i < 2; i++) {
+               ide_drive_t *drive = &hwif->drives[i];
+               if(drive->present)
+                       drive->unmask = 1;
+       }
+}

hopefully that will be early enough.
