Also, I implemented a proper (but still a hack) resource printer so you see all ranges. Before: pcm0: <Yamaha SA2> at port 0x220-0x22f,0x530-0x537 irq 5 drq 0,1 on isa0 After: pcm0: <Yamaha SA2> at port 0x220-0x22f,0x530-0x537,0x388-0x38b,0x330-0x331,\ 0x370-0x371 irq 5 drq 0,1 on isa0 This still needs more work to handle line wraps etc. Matthew Dodd did some work in this area for the EISA code which should be able to be used. Patch appended. I don't think it's too critical since ISA_NPORT_IVARS is the largest range, but the lower layers might end up trying to allocate on rids that the upper layers can't handle.
