/sys/dev/tc/xcfb.c has the following code:

---
static int
xcfbintr(v)
	void *v;
{
	int intr;

	intr = *(u_int32_t *)(ioasic_base + IOASIC_INTR);
	intr &= ~XINE_INTR_VINT;
	*(u_int32_t *)(ioasic_base + IOASIC_INTR) = intr;
	return (1);
}
---

(Yes, I stole the code from this.)
Should this also be handled in ioasic.c or not?
