Johannes,

			Thanks Johannes, you lifted off a big weight off my head. I have 2 more 
doubts.

	1) The allocation of minors, there have been a lot minor numbers left off 
between one card and the other.

say for eg,

Card 0 has minors 3,4,5,7
Card 1 has minors 67,68,69,71
Card 2 has minors 131,132,133,135

	as you see a lot of minor numbers have been left out say between 9 and 67, 
considering that minors are allocated as per the hardware requirements for 
various cards, which explains the minors from 0 to 8.



	2) with devfs, devfs is supposed to automatically allocate minors dependant 
upon the drivers. ie, the issue as stated earlier should not arise. I have 
the same scenario with or without devfs.

	The minor numbers do not change at all. I dug into the code and found that 
the nums2minor inline function is allocating the minors no matter whether one 
uses devfs or not.

	Is it possible to change this scenario, without impacting the normal 
behavior.

Manu
