Hi Lovemore,

I don't know if you got a reply from Epiphan, but these do appear to be
somewhat exposed.  When you run modinfo against the kernel module
powering the device there should be a line like

parm:           grab_flags:Grabbing mode (phased or port switch,
adapting alorithm, etc...) (int)

So adding the parameters to the script which inserts the drivers
*should* work.  These options, however, are untested and I have no idea
what valid parameter names or values would be.  For those you'd need to
talk to Epiphan, or just guess and check :)
