PERFORCE change 110777 for review

Change 110777 by mjacob at newisp on 2006/12/01 02:15:59

	Roll in some changes from the Linux/Mendocino side of the house-
	make ISPCTL_PLOGX find a handle to log into the management server
	with- not hope for the best. Change some things which were gated
	off of 24XX to be gated off of 2K login support.
