Yeah, it looks good, but if you don't want to install the debian
yourself(save time...), you may try the pre-installed one contributed
by Shiwei: http://www.bjlx.org.cn/loongson/install/
I have tried the lxde and gnome version, both of them run without any
problem. of course, no kernel image there, you still need to compile
one yourself. To install the pre-installed one there, you just need to
decompress the latest lzma package into your spare partition or
another Gkey.

Yeah, you may need to enable more options for the small defconfig may
miss some important options.
arch/mips/configs/lemote2f_defconfig is a good reference for you.

Playing with it is the best test, thanks and welcome your bug reports.
perhaps you can help to use the Fn keys(Fn+....) and the power
manager, wifi, backlight.... you need to install gnome-power-manager
of kpowersave(not sure which one does lxde has) to ensure the Fn key
works.
I finally managed to make loongson2_cpufreq driver work with the R4K
Timer, but need to tune some parameter to ensure the Timer works
without big offset. after finish it, will put it into our git repo.
The cpufreq driver is very important to ensure the machine is not too
hot, after trying it on my Gdium, the temperature monitored is about
53 C. but without this, it may be 65 or higher... With the help of
cpufreq, the notebook will be at least usable.
And BTW, currently, the battery driver can work well with the
gnome-power-manager, it can report the time to empty now ;-)
And Next, I will try PM(Suspend to disk and Memory) at first, and at
last, the audio/sound support.
Thanks & Regards,
Wu Zhangjin
