10.1 change kernel timer speed

Hi all,

Around the 2.6.13 time frame, the default timer speed changed from 1KHZ
to 250HZ :

The problem is I'm using Rosegarden (rg), which needs 1K and using the
RTC timer doesn't work - locks the system up actually when starting rg.


I know how to compile a kernel as I do some embedded work. My question
is:

After --> cd /usr/src/linux --> make xconfig , change timer speed -->
make --> make install ... Do I have to do anything else using just the
vanilla config , ie, grub ? Just reboot ? The README wasn't clear for
me here.

Thanks!
Robert
