[PATCH] 2.6.0-test11 IDE modularisation.

[PATCH] 2.6.0-test11 IDE modularisation.

[Gertjan van Wingerde]

Hi Bart,

Kernel 2.6.0-test11 suffers from the same IDE modularisation issues as the ones that got fixed in 2.4.23.
The patches below fixes this issue in the same manner as 2.4.23 does and work for me. 

	MvG,

		Gertjan.
