I would try patching the Samsung OF but I have no clue how. I only used a pre-patched D2 firmware. I got some D2 screens like the update and USB-connection to show but in limited blue colours and only under certain circumstances. I couldn't get it to boot Rockbox though.

Don't hesitate to ask the experts. Also, (I haven't looked but) I'm sure the instructions on flashing a D2 OF are written down somewhere (I guess in the wiki), those should pretty much apply to the P2 OF as well.

I really wouldn't advise flashing a D2 build to your P2, whether it's the OF, Rockbox, or otherwise. If you want to try anything like that, tcctool will do the job perfectly well, but without the risk of flashing permanently. You'd be crazy to try anything else.
To progress work on the P2, someone needs to set up a new Samsung P2 build target, as I suggested earlier in this thread. Then you can start making changes like setting the correct LCD height and width, and gradually getting other things to work.
The D2 LCD driver basically needs to be split into two: a common TCC7801 LCD controller driver which can run on both models, and specific things such as the LTV250QV control sequences would stay in a model-specific file. I'll look into making those changes.
Did anything else apart from the LCD work? I'd expect buttons, backlight, sound, power management and many other things to need specific P2 drivers...

I didn't pick up any sound from the P2 when it was running any of these D2 firmwares. If I could get the P2 to even boot Rockbox, I would have tried editing the screen sizes etc., although I'm not very knowledgeable on how I would go about all this Rockbox stuff. I have been using tcctool for this (as well as FWDN). What"works" is just the display (some quick pics I took: http://cid-9221f81e10b78ee2.skydrive.live.com/browse.aspx/P2%20Dev?uc=3&nl=1) and this is only when the P2 is connected via USB; once unplugged it just powers off. If you drop in the correct OF D2 update files, an update screen (or multiple ones?) of the same flavor show up and the light turns red (from the yellow/green); this is easily doable because the device is recognized as a Cwowon D2 USB device with an extra removable drive for the imaginary SD card reader. I know I'm not being very helpful; the short of it is that the Cowon OF runs -- very flaky on the P2, let alone not even having RB boot. I dunno what more help I can be but I'm always open to testing :)

Let me search the IRC logs.
edit: here, http://www.rockbox.org/irc/log-20090125, slyyf was the guy who tried it out. I talked with him over a few days.
