unmodified_drivers: update README from

and do not work with PVops but point towards the PVHVM functionality in
mainstream.

-To build:
+These drivers provide paravirtualised drivers for pre-PVops Linux
+kernels which have the classic-Xen patches applied. They do not work
+with kernels which are not patched with the classic-Xen patches. In

+For 2.6.36 and newer you should use the "PVHVM" functionality which is
+available in the mainline kernel.

+To build do one of:

    NB. You can override paths to Xen sources and a (stub) XenLinux
        build tree via the XEN and XL environment variable.
