+   PCI:        5, 9, 10, 11, 15 (mapped to UMIPCI inta, intb, intc, intd)
+   UMIISA:     10, 11, 12
+   SuperIO:    1, 3..12, 14, 15 (all may be remapped.  defaults as follows.)

+    USI:       3                (UART with Slow Infrared support)
+    UART:      4
+    FLOPPY:    6                (not currently used on shark)
+    PARALLEL:  7
+    RTC:       8                (not used on shark: RTC in sequoia used)
+    MOUSE:    12
+   Sequoia:    8                (internal RTC hardwired to irq 8)
+   Codec:      5, 7, 9, 10, 15  (irqe, connected to 15, has special status.)
+   CS8900:     5, 10, 11, 12    (P.14 of datasheet sez only 1 used/time)
+   FERR#:     13                (unconnected floating point error)
+
+total of 15 irqs:
+  timer, ide, 2 umi = isa/pci, ethernet, 2 codec, kb, usi, uart, floppy, 
+  parallel, rtc, mouse, ferr (irq 13)
+
+eventually, need to read the OFW dev info tree, and allocate IRQs.
+hardcoded for now.
