There was indeed a mix of old and new style module parameters and the driver 
doesn't like this.
I changed them all to old mode.

The new hack5 driver is at:
http://www.olifantasia.com/projects/gnuradio/mdvh/cx2388x
http://www.olifantasia.com/projects/gnuradio/mdvh/cx2388x/cx88-0.0.4-mdvh-hack5.tar.gz

It should now load clean and understand the new module parameters:
insmod ./cx8800.ko cap_raw_all=1 frm_size=2048

dmesg
cx2388x v4l2 driver version 0.0.4 loaded

I also changed the explanation of frm_size in cx2388x_tests1.txt
Since there is no parameter dwords. default frm_size=256 dwords=256*8=2048 was 
a calculation to determine frm_size, not two parameters.
It now reads:
So, since 256 dwords is 2048 bytes, possibly the default should be: 
frm_size=2048

Good luck,
