I had a dual-boot on my iPod and everything worked in linux, I could even play pong on the iPod - err.. except for some reason it wouldn't play music;-) - not sure what was wrong but the dual-boot seemed to work without problem - you can check if your iPod model is supported here: http://en.wikipedia.org/wiki/IPodLinux ... if its an old enough model, I think its fairly safe to give it a go...
My iPod eventually fubared due to hard-ware reasons, so unfortunately haven't been able to pursue that course myself..
Best've luck, Sanjay
mine is iPod Classic which is latest model which is not yet supported by IpodLinux or Rockbox...i can only wait to get Linux on it :-)
