dkms build error mptlinux drivers

[dushy]

Hi Matt,

Thanks for the help. I was checking lsmod output for the the default
Redhat ES kernel and found a module mptscsi which was not built on the
2.6.19.1 kernel and hence thought the drivers are required for the new
kernel too.

But looks like the module mptscsi is not required and I commented out
this entry in modprobe.conf before mkinitrd and the system now
recognises both the RAID drives when with kernel 2.6.19.1
