PC-style RTCs do work with genrtc, even on LongTrail (I used ppc_rtc last time I booted my longtrail). And it would be really nice if someone would add the missing features (I _think_ alarm is the only important one, aside from /proc bits maybe) to genrtc. :) -- Tom Rini http://gate.crashing.org/~trini/
