Why you want to use message-queues in kernel ?? for different
processes/modules to communication ??? If so then you can do this by
calling functions from one module/process to other module/process or
through memory sharing etc .... b/c in kernel each module/process when
loaded becomes the part of the kernel and they can interact with each
other through function calling ....

There might be some way of implementing msg-queues in kernel but I
havn't found any till now and don't know abt that !!!!!
