I haven't used the cpufreq ondemand in the kernel itself....

I wonder if 2.6.29 does better ;-)....
I would have thought you do have ondemand support in the 2.6.28
   kernel if its' appearing in /proc /sys etc...

You could use the workaround of installing 'powernowd' (simple and
   known to do what you want), with the kernel set for "userspace"
   governing...
