Amasingly, the em28xx driver just works! At least with kernel 2.6.24.6. But the user-space tuner driver is currently not available.
The signal strength of DVB-T seems to have improved over the last time I tried (one year ago). Now I can even watch TV without moving the antenna close to the window
Here are the transponder settings for Austria (as they come with Ubuntu 8.04):

The Powershot A720 is a bit different compared to the IXUS 70; it runs on Canon's own DRYOS (instead of Windriver's VxWorks), it runs on regular AAA batteries, and it loads the CHDK firmware only on boot. So one has to make the SD card bootable in order that the DISKBOOT.BIN file get loaded.
And the image sensor seems to be of higher quality.
