http://www.ps3news.com/PS3-Hacks/gui...-ubuntu-10-10/ Since you already have the kernel module, you just have to compile the payloads. The annoying part is installing the toolchain so you can cross-compile for the PS3. It takes a while to compile the tools. Thankfully, you only have to do that part once. After that you just update the pl3 submodule, add any patches, and recompile. Then you can copy the .bin to your N900 and be happy. Edited to add: My bad, for some reason I misread HEX file as source file.
