Because it's the kernel that runs on the N900 hardware? Anyway, I'll post a few more details over in my Android 2.0 thread http://talk.maemo.org/showthread.php?t=35112 eventually - it's pretty straightforward, just cut out the PMEM-dependent framebuffer code and modify the boot configs, compile, and copy the rootfs on over - it'll run with Solca's old NITDroid kernel although I suspect a new kernel with PMEM support would be faster when it comes to the framebuffer.
