PATCH: cpqarray.c boot prams support for 2.3 kernels

Hi,
In order to use the Compaq array driver with EISA SMART controllers
you have to specify something like 'smart2=0x1000' at boot time.
That no longer works with 2.3 kernels, due to kernel changes.
The patch below fixes it.

I also noticed that 2.2 kernels have cpqarray.c version 1.0.5 while
2.3 kernels have version 1.0.4. Is that deliberate?

Richard
