Hi there.

I'm using 10.04 since beta2 and the problem is the same. I'm using:

echo 15 > /sys/devices/system/cpu/cpu0/cpufreq/ondemand/up_threshold
echo 15 > /sys/devices/system/cpu/cpu1/cpufreq/ondemand/up_threshold

in /etc/rc.local to help the system speed up when required.

I haven't really tested the behavior described, but flash is indeed slow
with ondemand and not triggering cpufreq to use higher frequencies
without this workaround. I'll test mainstream kernel but it may take me
more than a week as I'm going to week long holidays tomorrow. If I won't
write anything, please write a note to chase me - I'm more than happy to
help Ubuntu community, but I have a tendency to forget about things to
do. :)
