>Description:
Do we not support large resource data item in PNP Dependent Functions ?
in Current branch, last commit  for file /sys/isa/pnpparse.c seems 
removed possibility of supporting large resource data in  Dependent
Function, and only support global large resource data item.

http://www.freebsd.org/cgi/cvsweb.cgi/src/sys/isa/pnpparse.c.diff?
r1=1.11&r2=1.12&f=h

if I am right, the start==NULL should be removed.
