I guess we could get Fremantle running on N9/50 if we had a decent kernel runing there, see the N9/N950 upstreaming force.

For Maemo, you need to enable CONFIG_SYSFS_DEPRECATED and CONFIG_SYSFS_DEPRECATED_V2. I recommend using Pali's kernel which is more complete as it includes extra patches that are yet to be mainlined. The two SYSFS options are already enabled in Pali's config.
Are there already somewhere kernel patches which are needed for Maemo5?

felipec did the gst-dsp user space work for both the N900 and N9 at Nokia I believe. I don't know if it got upstreamed. If not, have a look here:

So which would be the best choice for the basement kernel development, start with pali's and patching for a1 or start with a1 and patching maemo/Nokia SGX?

However I like the idea to have another device, which is not only for hacking and development and runs maemo.

So I can't use binary stuff from N900 for the first try?

gst-dsp and gst-omapfb were added to buildroot but not sure if they were upstreamed yet. However they were removed when gst-ffmpeg was replaced by gst-libav as they are not available for gstreamer-1.0.

Thanks!
However this generate more questions.

The beagle kernel and defconfig link are no more valid.
Does somebody can upload them for me?
