The SIGSEGV is being tracked in bug #1039916 "Nvidia driver causing SIGSEGV in nvclock and smartdimmer".
That bug affects the "Fix released" status of this bug since this work-around no longer functions. I've nominated this bug for Precise and Quantal, but any fix of the SIGSEGV issue will be done in bug #1039916.
