Some of the VIA pm and propm devices are actually the same device as the

PCI-ISA bridge.  Thus, when viapm0 or viapropm0 attaches, isab0 dosen't
attach so there is no isa0 bus hung off of that bridge.  In the non-ACPI
case, legacy0 will add an isa0 anyway as a fail-safe, but ACPI assumes that
any ISA bus will be enumerated via a bridge.  To fix this, call
isab_attach() to attach an isa0 ISA child bus device if the pm or propm
device we are probing is a PCI-ISA bridge.  Both drivers now have to
implement the bus_if interface via the generic methods for resource
allocation, etc. to work.  Also, we now add 2 new ISA bus drivers that
attach to viapm and viapropm devices.
