I submitted this earlier today against an older kernel version; this is
a new patch against 2.6.12-rc4
The bttv module currently lacks support for the Adlink RTV24 capture
card. The following patch adds support for the Adlink RTV24 video
capture card to the bttv module.
In case my mailer mangles spaces/tabs, patch is available at
http://argo.peterskipworth.com/kernel/adlink-rtv24-patch.txt
