The kernel and tinboot code only occupy the first 6 MB or so of NAND. I think we could safely shrink the starting point to 16 MB without any fear of overwriting stuff. How does this look:

mtdparts=msm_nand:
0x20000000@0x0(nand) - 512 MB total
0x00800000@0x01000000(root) - 8 MB of space
0x0A000000@0x01800000(system) - 160 MB of space
0x14800000@0x0B800000(userdata) - 328 MB of space

I think 160 MB might be a bit much for system, but that does give the chefs a lot of space to work with. 328 MB for user data will really be 310 MB of usable space since we are eating up 18 MB with modules.
You guys are better at this than me so whatever you think its best.

Nate: i explained the root, i need it for kexec. Its so we can make kernel updates without flashing. Now the everyday user doesnt really need this since they will stick to a stable releases, but for us it wll help so we dont burn our phones constantly flashing.

Also i thought you wanted a cache parititon. throw it in there if you want to mess with it. Not sure what to do with it but hey, let the creativity flow. ALso we can keep the kexec for dev only and share it for cache ?

Edit: also here is another test RIL
