FYI, 

as the 2 syslog extracts show;
1.   the new kernel is now detecting the buggy TSC on the GEODE-sc1100
2.    the bug is apparently correctable by passing 'idle=poll' on kernel 
boot-line.

Heres one vendor's bug/erratta description:

Its nice to see the buggy TSC detector detect, and the work-around work.
