It looks like the cause of this is that siisata is trying to use the
SiI3114 in this system, with which it is (as far as I know) not compatible.

With "no siisata" in the kernel config file, things are much better:

satalink0 at pci1 dev 5 function 0: Silicon Image SATALink 3114 (rev. 0x02)
satalink0: 33MHz PCI bus
satalink0: bus-master DMA support present
satalink0: using ioapic0 pin 19 for native-PCI interrupt
atabus0 at satalink0 channel 0
atabus1 at satalink0 channel 1
atabus2 at satalink0 channel 2
atabus3 at satalink0 channel 3
satalink0: port 0: device present, speed: 1.5Gb/s
satalink0: port 1: device present, speed: 1.5Gb/s
wd0(satalink0:0:0): using PIO mode 4, Ultra-DMA mode 6 (Ultra/133) (using DMA)
wd1(satalink0:1:0): using PIO mode 4, Ultra-DMA mode 6 (Ultra/133) (using DMA)
