Well, I couldn't wait and installed 10.04 RC yesterday.
In short: the problem still exists.
The em28xx drivers seem to work fine, but the xc2028 driver (which is also the driver for the xc3028 chip on the terratec xs) doesn't work with the firmware provided in linux-firmware-nonfree:

$ dpkg -S /lib/firmware/xc3028-v27.fw
linux-firmware-nonfree: /lib/firmware/xc3028-v27.fw

The long story is: my device still has a wrong usb id (eb1a:2871). So it is not being loaded at boot time, because no driver is responsible for this usb id. So I installed linux-source, added eb1a:2871 to the identifiers of the terratec xs (/usr/src/linux-source-2.6.32/drivers/media/video/em28xx/em28xx-cards.c) and compiled my own kernel with ubuntu's config (/boot/config-2.6.32-21-generic). It worked fine, the driver was loaded on boot time.
