I'd have to install 5-something and incremently test it. What I can say is 
that I remember that for a while it worked with simply putting the (wrong) 
product/manufactorer ID that was reported in card.c and treating it as 
hauppauge, but later the reported ID became 0xffff and that went nowhere. It 
could probably have been done better and perhaps work with something 
analogous to what Robert Krten wrote.

I also have a miro card and a saa based avermedia one, so I pretty much tossed 
the wintv aside.

I have an amd box here that I need to set up for testing, I'll look which 
install images I still have a CD for and slap in the hauppauge and see if I 
can recreate that situation a little. If I can point to some useful 
timeframes where things broke I'll let you know, if not, well I won't :)

IIRC it was between 5.2 -> 5.3 (hack as described above needed)
and 5.3 -> 5.4/6.0 (b0rken since)
