Erm, CONFIG_HZ is not related to the RTC. And i didn't know a kernel compile

to let us know more [i.e. the name of the config option?]..
Lee's proposal was to change the default max frequency an ordinary user could
set the rtc to from 64hz to something usable like 1024 hz. I would even plea
for going higher.. I.e. 4096hz.

hey,
I just took a good look at my config, an the default actually is 1024
(at boot time). My kernel is 2.6.18. For quite a few versions now I
had an option called CONFIG_HZ_1000 that is used to set the boot time
default value.
