Yes it is possible, in fact I tested a new kernel (zImage) last night that makes 384 MB available (compared to 256 MB right now). It boots unbelievably quick (like less than 15 seconds!) and the phone runs much smoother, really amazingly quick. When I boot up Android with only 256 MB of RAM allocated to it, I have a maximum of 120 MB free (usually less like 115, 110 or less).
With 384 MB allocated i had about 250 MB free, much better. Last night's kernel had some issues left (wifi not working, issues waking up).
Apparently it's been fixed already so we should have a new kernel available today.
Cotulla on his end is working on getting the 512 MB kernel working and he's close apparently. I think the remaining memory (the remaining 64 MB) will be used for the system or for the 3D buffer..... Not sure though...
Also your current Android build will work fine, all you'll have to do is replace the zImage and edit the startup.txt (to change the memory allocation values) and that's it. It might get a little bit more complex (like maybe replacing the wifi module) but all in all with proper instructions you should be able to do it in a few minutes.
Well let's wait and see... But 384 MB available already makes a huge difference so that's great news...
Hope this helps....
