Hello Andrew, I have same DVB-S2 card on a Debian Squeeze system, I
have installed this way:

mkdir /usr/local/src/dvb
cd /usr/local/src/dvb
wget http://tevii.com/100315_Beta_linux_tevii_ds3000.rar
unrar x 100315_Beta_linux_tevii_ds3000.rar
cp dvb-fe-ds3000.fw /lib/firmware/
tar xjvf linux-tevii-ds3000.tar.bz2
cd linux-tevii-ds3000
make && make install

It works for me, sometimes I have those message on /var/log/messages:

May  4 13:43:14 htpc kernel: [11575.306168] ds3000_firmware_ondemand:
Waiting for firmware upload (dvb-fe-ds3000.fw)...
May  4 13:43:14 htpc kernel: [11575.306181] cx23885 0000:05:00.0:
firmware: requesting dvb-fe-ds3000.fw
May  4 13:43:14 htpc kernel: [11575.358334] ds3000_firmware_ondemand:
Waiting for firmware upload(2)...

But it works well, I use it with MythTV, SD and HD channels.

Let me know if you need some test.

Kind regards.
