Bug#440377: eats laptop alive

[Joey Hess]

Package: hex-a-hop
Version: 0.0.20070315-3
Severity: normal

When I'm playing hex-a-hop, the ondemand governor scales my cpu
frequency all the way up to 1.2 GHz. That cuts my batter lifetime in
half, it also makes the laptop uncomfortably warm to the touch after a
while.

I found an old patch for this at
http://forum.caravelgames.com/viewtopic.php?TopicID=8902&page=1
which I have cleaned up to work with this version.

This adds a 10 ms delay after each graphics update. This does not affect
responsiveness any, and lets the game run only using 800 MHz here (quite
close to the 600 MHz minimum CPU cpeed of my laptop). The only downside
is that animations run marginally less smoothly.

I can get the same result by just forcing my laptop to never run faster
than 800 mhz, but that doesn't allow me to do other cpu-intensive
things, such as compiles, at full speed, while also running hex-a-hop. I
wonder if the delay could be enabled as an option. A command-line option
would be fine for me.
