    usr.sbin/acpi/acpidump acpi_user.c acpidump.h 
  Log:
  Instead of scanning the entire lower 1 MB of RAM, only scan locations
  where the RSD PTR can actually occur.  According to section 5.2.2
  of the ACPI spec, we only consider two regions for the base address:
  
      1. EBDA (0x0 - 0x3FF)
      2. High memory (0xE0000 - 0xFFFFF)
  
  I don't know whether this fixes any actual problems but is more correct.
