I take it that something like 'isapnp* at isa?' is quite uncommon?

I now have iic attaching to viapcib, but it just occurred to me that to
attach to iic I need to specify an 'addr'. How does isapnp@isa get
around this? Is it simply possible because ISA doesn't have strict
requirements on attach args? Will anybody scream bloody murder if I make
'addr' optional in i2c_attach_args?
