linux on polaroid pmp350-4 mp3 player?

I am trying to re-flash and put linux on this mp3 player. The ultimate goal is full sound and photo/video support with touch screen interface, using an alternate OS other than the one provided by polaroid. I would like to use this to read text documents as well.

I was going through some of the old gadgets in my house and found that I still had an old polaroid pmp350 mp3 player. It has a touch screen and I thought to myself "hmm... google android..." or "rockbox..."

This is a cheap peace of hardware, and even though google android is out of the question, I was wondering about flashing it with custom firmware to allow it to run some other operating system. It has a touch screen which would make it quite fun to play around with if only there was a way to expand its current capabilities.

So I thought I would put up this thread to see if somebody more clever than I could figure out how to re-flash this thing and install linux, OR if somebody could point me in the direction of materials that might be used to do such a thing.

The main issue is going to be getting an OS to run on this unsupported hardware.

I am going to be doing research in the meantime to find out how to get linux on this device, because I think it would be a really cool hack to show off to friends.
*Update* Have written polaroid for info regarding technical specifications, also asked if they might be able to provide a rom flashing tool*

If anybody wants to give this a shot, let me know how it turns out.

Peace and love.

I have a pmp700-4 mp3 player, and trying to do the same thing. Maybe possible to connect via telnet?
