The patch is against v4l-dvb, but I am using it with kernel  2.6.22. I change 


EXTRA_CFLAGS = -Idrivers/media/dvb/dvb-core/


= -Idrivers/media/dvb/dvb-core/ -Idrivers/media/dvb/dvb-usb/ -Idrivers/media/dvb/frontends/

I had also 500.timing patch, but I think that is not important.

The patch 500.streaming and the patch 500.disconnects do the same thing.
I don't know why you can't make it work with MythTV. The card behaviour must 
be the same with or without the patch.
