Hi Pavel,

There is the Mitac Mio A701. Very old but still it is there, with the kernel
part maintained.

Userspace was based on QTopia in 2008. I don't maintain that part anymore
though.

The GSM part relies on a simple ttyS device (modem has its internal flash), no
real data at that time, or rather 2G only, but the 07.10 mux support was never
included in Qtopia ...

Cheers.

Thanks for the info. 

I added 

"
+Mainline has support for Mitac Mio A701, but that having only 64MiB
+RAM, QTopia is the software to use there.

Thanks Pavel, that looks good.

+Running Linux on Cellphones
+===========================
+
+At this moment (2014), there are no cellphones completely supported by
+mainline kernel. Another problem is lack of hackable userspace to run
+on cellphone, even when kernel support is available.
+
+Openmoko was first phone running Linux with X. GSM support there was
+based on freesmartphone.org daemons.
+
+Sony has project to merge kernel support for Xperia Z1.
+
+Nokia N900
+----------
+
+Nokia N900 orignally shipped with Maemo-based userland, which is close
+enough to GNU/X/apt based Linux; key components communicate using dbus
+and application can be written in pygtk. Kernel patches were
+relatively clean, and the core stuff is merged, unfortunately there's
+quite a lot of non-core stuff and pieces of userland are closed
+source; including some critical support such as bridge between CPU and
+modem for voice calls.
+
+Unfortunately, that means that kernel development is hard, because it
+is non-trivial to test all the various devices in the phone due to
+lack of suitable userspace and userspace development is hard, because
+there's no suitable kernel to work with.
+
+Here are instructions for getting usable userspace for kernel testing,
+and suggestions for some tests. Setting up nfsroot (needs non-mainline
+patch) is strongly recommended for development.
+
+I'm using Debian 7 for testing/development. It works well including
+touchscreen and X support, as of 3.18-rc1. Instructions are here:
+
+https://wiki.debian.org/n900-wheezy-armhf
+https://wiki.debian.org/MaemoAndSqueeze
+
+Following packages are useful on N900:
+
+libts-bin evtest ntpdate module-init-tools udev netbase ifupdown openssh-server
+locales whiptail less mpg123 mplayer ofono gcc strace mdbus2
+
+This calibrates display to usable state on recent kernel and Debian 7:
+
+DISPLAY=:0.0 xinput --set-prop --type=float 8 115  1.10 0.00 -0.05  0.00 1.18 -0.10  0.00 0.00 1.00
