[mythtvnz] Tevii S421 DVB-S cards on Linux

[Austin]

Anyone had any luck with Tevii S421 DVB-S cards?
Running Debian 'Squeeze' amd64, kernel 2.6.36.4.
It shows up as a USB device, which is odd as it's a PCI card:

$ lsusb
...
Bus 005 Device 002: ID 9022:d421 TeVii Technology Ltd.
Bus 004 Device 002: ID 9022:d421 TeVii Technology Ltd.

But the real problem (I think) is the failure of the driver.
I downloaded the driver:
	hg clone https://bitbucket.org/liplianin/s2-liplianin-v37
Initially the build failed because two header files were missing:
	media/noon010pc30.h
	media/sr030pc30.h
but after I acquired them from elsewhere, it finished the build.
However, there were several warnings of this general form:

WARNING: /home/austin/projects/tevii-37/s2-liplianin-v37/v4l/rc-core: 
'ir_raw_handler_unregister' exported twice. Previous export was in vmlinux

Relevant lines from dmesg after driver install and reboot:
