It is possible, but it's a bad idea because non-standard values can 
result in driver breakage.  Some code assumes specific timer 
granularities (100Hz = 10ms, 250Hz = 4ms, etc).  This usually happens 
with values above 1000Hz, so it might be possible to experiment with 
non-standard sub-1000Hz values.

But why do you want a custom value anyway?
