I believe the filesystem still needs mounted, I am thinking the nandsim approach is needed, and the pagesize might need to be set to 4096, but these are all guesses for now

I am very interested in this. My N900 is my spare phone so I may be able to help with testing in the future, after July 3rd, when I return back home.
Keep up the great detective work!

This thread is really interesting to follow. So basically since the N950 uses the same SoC the OS can be ported to work on the N900 (in theory at least)?

Code:
$ grep THUMB arch/arm/configs/rm581_defconfig CONFIG_ARM_THUMB=y # CONFIG_ARM_THUMBEE is not set # CONFIG_THUMB2_KERNEL is not set

Code:
Features : swp half thumb fastmult vfp edsp thumbee neon vfp3
In other N950 related news, it has a C64x DSP! Everything Maemo 6 should work fine, except probably omap34xxcam.

IIRC, thumb and thumbee are missing from certain hardware revisions of the N900. Not on mine though.Code:Features : swp half thumb fastmult vfp edsp thumbee neon vfp3
