Still no dice on the iBook (actually works worse than rev 2, which at
least booted and didn't die until I started trying to eject the CD and
make real use of the disk).

wdc0 at obio0 offset 0x1f000 irq 19: DMA transfer
atapibus0 at wdc0 channel 0: 2 targets
cd0 at atapibus0 drive 1: <MATSHITADVD-ROM SR-8176, , MA24> type 5 cdrom removable
cd0: drive supports PIO mode 4, DMA mode 2, Ultra-DMA mode 2 (Ultra/33)
wd0 at wdc0 channel 0 drive 0: <IBM-DJSA-220>
wd0: drive supports 16-sector PIO transfers, LBA addressing
wd0: 19077 MB, 16383 cyl, 16 head, 63 sec, 512 bytes/sect x 39070080 sectors
wd0: drive supports PIO mode 4, DMA mode 2, Ultra-DMA mode 4 (Ultra/66)
conf = 0x11823, cyc = 4 (120 ns), act = 3 (70 ns), inact = 1
wd0(wdc0:0:0): using PIO mode 4, DMA mode 2, Ultra-DMA mode 4 (Ultra/66) (using DMA data transfers)
cd0(wdc0:0:1): using PIO mode 4, DMA mode 2, Ultra-DMA mode 2 (Ultra/33) (using DMA data transfers)

Only got as far as "root on wd0a dumps ob wd0b" before spewing errors
(all with zeros in the parameters; they didn't make it into the
message buffer, though).
