I don't recognize the dvb_p11 module.  I have an HD-3000 running on 
Fedora Core 3 with the 2.6.12-rc3 kernel and the key module I have 
installed is cx88_dvb.  Here's some of what lsmod shows running on my 
system.  Note I also have a WinTV PVR-350 installed in this system:

[root at mythtv-1 linux-2.6.12-rc3]# lsmod | grep -i dvb
cx88_dvb                9540  0
cx8802                 14916  1 cx88_dvb
mt352                   9092  1 cx88_dvb
or51132                11524  1 cx88_dvb
video_buf_dvb           8964  1 cx88_dvb
cx88xx                 62304  3 cx88_dvb,cx8802,cx8800
video_buf              30148  6 
cx88_dvb,cx8802,video_buf_dvb,cx8800,cx88xx,bttv

(for some reason I also have dvb_core statically compiled into my kernel 
- don't recall why - but that's why it's not showing up as a module)

If you have /etc/udev/rules.d/10-pchdtv.rules and 
/etc/udev/permissions.d/10-pchdtv.permissions then this should be all 
set.  It's probably because the right modules aren't being loaded that 
these aren't doing anything.  They won't be referenced until the drivers 
for the hardware are properly loaded & initialized.  If you want, 
however, you can edit /etc/udev/udev.conf and change udev_log to "yes". 
  This will output some debugging information into the syslog.
