I have modeified the dvb/btxxx drivers to allow for more than 4 cards and all cards now work using dvbscan etc. All nodes /dev/dvb/adapterX etc are set up correctly by udev. However, mythtv-setup does not allow me to configure more than 4 cards DVB0 through DVB3 without returning an error message. I am at work right now and cannot check the exact error displayed, but will post the error message once I am back home.

I managed to solve this myself. If anyone else should be interested in 
how to do this, the changes necessary to make mythtv support more than 4 
dvb cards are:

* change mythtv/libs/libmythtv/dvbdev/dvbdev.c to include the number of 
nodes/adapters you have/need - given the structure of the file the 
changes should be intuitive.
* if you need MORE than 8 cards, you also have to change 
mythtv/libs/libmythtv/videosource.cpp. Search for "DVB Card Number" and 
change the "SpinBoxSetting" two lines above the search result from 7 to 
the desired number n, where n = no. of dvb cards - 1
