What do those *'s mean in your modprobe conf? They should be numbers.
You should have :

alias char-major-81-0 bttv
alias char-major-81-1 ivtv

so that the bttv card connects to /dev/video0 en the ivtv one (pvr150) to /dev/video1

Also, you are missing a firmware file for the pvr150. 
cx25840: Unable to open FW file '/lib/modules/HcwMakoA.ROM'
See the ivtv wiki or mailing list on where to get that file.
