Ok, I did:
wget
http://fedoraproject.org/wiki/Bugs/FC6Common?action=AttachFile\&do=get\&target=kernel-fix.sh
Install/reboot/etc.
and modprobe gspca
and then I see the following in lsmod:
lsmod
Module Size Used by
gspca 643792 0
videodev 29633 1 gspca
v4l2_common 26945 1 videodev
v4l1_compat 16581 1 videodev
radeon 116065 2
drm 78421 3 radeon
----------- snip -------------------
I still don't see a /dev/video but this appears to be a step forward
anyway.
Thanks.
