power management on beige g3

["Nathan S." <farruinn@hotpop.com>]

How does one get power management on an oldworld G3?  New-world has PMUD 
(right?), but I beleive that I have a CUDA ... whatever that means.
Any attempt to find information on my own has been futile =(.  If anyone 
can help me out (even if it is to tell me IT CAN"T BE DONE) then I'd 
appreciate it.

Thanks,
Nathan
