One of my systems needed Real Time Clock -> PC-style 'CMOS' enabled in
the kernel to prevent a Hardware Clock error at startup and to make
the 'hwclock' command work. Another of my systems doesn't have Real
Time Clock kernel support enabled at all, and yet 'hwclock' works
fine. Does anyone know how that works?

It might have something to do with the "High Resolution Timer Support"
option (in "Processor type and features".) Not sure though.

Thank you but none of my systems seem to have that enabled.

One thing I would try is examining the output of dmesg. Maybe something
relevant shows up.

Thanks, does anyone know where this has gone in 2.6.28:
Device Drivers -> Character Devices -> Enhanced Real Time Clock Support
Or what the variable name might be so I can look it up that way? I
couldn't find it by searching for RTC in .config.

$ grep RTC .config
CONFIG_HPET_EMULATE_RTC=y
CONFIG_RTC=m
CONFIG_GEN_RTC=m
CONFIG_GEN_RTC_X=y
Found under Device Drivers -> Character Devices
