See the PnP spec, section 4.3 on the I/O Range Check register for the 
major solution to this problem.  See your BIOS for the IRQ/DRQ 
allocation configuration options (ISA/PnP toggle).  

The only losing case now is a system with no ECSD support, ie. "legacy" 
hardware.  A userconfig-level "list of available IRQ/DRQ" option sounds 
pretty good here.
