That's true. According to the STV0299B datasheet, only registers 0x01, 0x02
and 0x03 are accessible in standby mode.

I haven't looked at the code, but shouldn't a proper standby mode also
include setting the SAA7146A's GPIO pin 2 to LOW? AFAIK, that pin is used
to power down (or reset) the frontend on all TechnoTrend-designed cards. If
you set that pin to low and then to high again, the STV0299B will _not_ be
in standby mode and can be properly detected.
