Looking at NetBSD-1.4/arm32 on my shark, there's quite a few things
which show up as not configured:

dma-controller@i00 at ofisa0 not configured
interrupt-controller@i20 at ofisa0 not configured
timer@i40 at ofisa0 not configured
configuration@i15c at ofisa0 not configured
mouse@aux at ofbus2 not configured
power@i380 at ofisa0 not configured
eeprom at ofbus3 not configured
midi@i330 at ofisa0 not configured
pci at ofbus1 not configured
display@it3b0 at ofbus1 not configured

does -current provide any more drivers for the above ?

If not, are there any online docs for the above which would
help in getting drivers written for them ?
