Revert "PNP: increase the maximum number of resources"

This reverts commit fc175adc.

There have been reports that it causes problems:
	http://bugzilla.kernel.org/show_bug.cgi?id=9514


people are still debating for 2.6.24 if it should be reverted or not,
but as it causes a known problem, we will revert this for now.
