Thanks for the hint, that sounds promising. However, I didn’t 
have /sys/classes/rtc and since I didn’t know what I need for my ICH-7 
chipset, I compiled everything I could find under Device Drivers/RTC. Then I 
loaded all those modules, but apart from an empty directory /sys/classes/rtc, 
the only reaction at all that I got in my syslog was:

kernel: rtc_cmos: probe of 00:07 failed with error -16

:(
Well, I’ll dig into it further...
