As promised in the 1.3b release, I just uploaded a patch for RapidDisk 1.3 to be able to build and install the module on the older 2.6.18 Linux kernel. That is, if you are still using Red Hat or CentOS 5.x. To apply the patch, just navigate to the module/drivers/block path from the root of the project package, make sure the patch is copied in there, and type:

$ patch -p0< rxdsk1.3_linux-2.6.18.patch
