end for isa(4). o Add a seperate bus frontend for acpi(4) and allow ISA DMA for it when ISA is configured in the kernel. This allows acpi(4) attachments in non-ISA configurations, as is possible for ia64. o Add a seperate bus frontend for pci(4) and detect known single port parallel cards. o Merge PC98 specific changes under pc98/cbus into the MI driver. The changes are minor enough for conditional compilation and in this form invites better abstraction. o Have ppc(4) usabled on all platforms, now that ISA specifics are untangled enough.
