In my system log file, after the END IVTV, ivtv-osd tells me which the
frame buffer device is:
ivtv: ==================== END INIT IVTV ====================
ivtv-osd: Framebuffer module loaded (attached to ivtv card id 0)
ivtv-osd: Framebuffer is at decoder-relative address 0x00510000 and
has 1704960 bytes.
ivtv-osd: screen coords: [0 0] -> [720 480]
ivtv-osd: original global alpha = 208
ivtv-osd: current OSD state = 39
ivtv-osd: new global alpha = 208 (1 255 0)
ivtv-osd: framebuffer at 0xed510000, mapped to 0xea061000, size 1350k
ivtv-osd: mode is 720x480x32, linelength=2880
ivtv-osd: fb2: iTVC15 TV out frame buffer device
My /dev/fb2 is a symbolic link to /dev/fb/2 so the permissions on
/dev/fb/2 are the important ones for me. Your kernel might set things up
differently.

I'm using the 2.0 drivers. Don't know if that makes a difference.
