In 2.6, we already have sufficient changes for Intel IPF Compiler to build the kernel, especially intrinscs changes, and you should not need a patch. To make it faster, we might want to use PGO (profile guided optimization) provided by the compiler; yes, it's available even for the kernel with a driver.
Thanks, Jun
