I finally found some time to debug this and found two problems:

* insufficient matching of PCI IDs (there was a mask of 0xff0 being
used, but recently Nvidia released GPUs with 0x1XXX PCI IDs that were
erroneously being matched and handled as a wrong class
==> using a mask of 0xfff0 now

* failures to mmap PMC (without error handling) leading to unaccessible
memory
==> error out if PMC could not be mmap()ed

A patched version has been just uploaded to sid. Please try it.

It is possible that nvclock no longer works with newer cards and/or
newer drivers, but it should no longer segfault.
