State-of-the-art is using programs which throttle CPU. This saves energy & you get more reading time.
rincewind modded iRex's pdf viewer this way & added some nice features like "remembers pen-settings" or "Hide scribbles". He uploaded the binary in this thread
on forum.irexnet.com. Thanks, rincewood!
I attached a installation & deinstallation script.
Oh, Adam B., I hope you get a unbricked iLiad in near future. Therefore I run the script several times, did a reboot, tested the firmware check; I found no problem: so it should be safe for all.
[EDIT]: I updated ipdf binary and changed readme.txt a bit in zip file [rincewind's Mar 23, 2007 version, md5: a6a2650badb6007a34158b064293c6d3 changes: stripped binary, not working easter egg removed.]
[EDIT II]: fake FAQ: Ok, some new ipdf binary was released. I have installed a older ipdf with the script. Do I have to deinstall ipdf with the older script before I can install the new ipdf binary? No! Just remove the old script on MMC/CF, copy the new script to it & execute the script.
