You can patch your 2.4-ts11 kernel with a linux-2.4-ts11-hrt.patch.gz from 
Files section. It improves gettimeofday resolution to the microsecond level, 
and fixes a bug (yes a BUG) with real time sliding away some 15 seconds a day 
because of wrong calculation.
Patch works very well, and time keeping comes back to maximum slide of 5 
sec/day which is what is possible with a given hardware.
Make note that this is not the same as having kernel scheduler working at 
1021Hz - your task scheduling still happens with 10ms resolution.
Anyway this patch does not affect performance as a 1021 clock does and is safe 
to apply.
