It is supported under Linux.

Making it work
This card should work out-of-the-box. These instructions are obsolete for any modern distro.
Required modules and parameters:

First of all, you need to enable the video for linux core support. Then we make use of the V4L API 1.
<*> Video For Linux [*] Enable Video For Linux API 1 (DEPRECATED) --- Enable Video For Linux API 1 compatible Layer Video Capture Adapters ---> Radio Adapters ---> Digital Video Broadcasting Devices --->
Now we need to include the cx88_dvb module as shown below.

Then we dive into the DVB configuration menu. I'm quite unsure what is relevant to use the card. Thats why i've selected the whole stuff ;)

Last but not least, the frontend section needs our attention. That's the same as above. I'm not sure if you really need these modules. You can built them and use the trial and error method to determine which modules are necessary and which are obsolete.

Then do a make && make modules_install.
To load the modules, i've only done the following:
All the other necessary modules will be loaded automatically.
lsmod returns the following:

To test if your card works, you can use the dvbscan app with the appropriate options. For example a scan in germany with Astra-19.2°E looks like.
dvbscan /usr/share/dvb/scan/dvb-s/Astra-19.2E >> channels.conf
Once you have a good looking channels.conf, you can try to get the time from the sat.
Tune into the first channel of the conf file.
szap -c channels.conf -n 1
and then open a second term and get the date via
