As a follow up to my own message, I found the following dump of the
segmentation fault in my system log:
Unable to handle kernel paging request at virtual address 76747679
printing eip:

This happened on the initial attempt with ivtv-detect or ivtvctl. I
had tossed in some debugging fprintf's into the ivtv-detect.c source
and this seems to happen on
fd = open(devices[i], O_RDONLY);
Does this help any?
