I tried to figure out from your patches what are actual changes vs.
2.6.33 (as opposed to merely backports, which seems to be most of it).
So I ended up using the Lemote kernel tree, after merging back the linus
2.6 tree.
I also enabled the staging driver sm7xx for the display adapter. Any way
to avoid building it into the kernel? Otherwise I don't seem to get a
console.
It seems to hang after working for a while. Though maybe this is
something to do with attempting to play video (video playback doesn't
work well).
The webcam only seems to work with luvcview and not with anything else I
tried.
As I want to aim for a system supported in squeeze: any idea if squeeze
would have 2.6.32 or 2.6.33?
Another issue: surprisingly powertop actually works there. But it keeps
showing the system using the full clock clock frequency of 800Mhz. I
have not yet tried to build the kernel with CONFIG_TIMER_STATS to see if
there are any offenders. But I don't suspect so (I have not tried to
install DAHDI yet, which will be such an offender).
I see that the module loongson2_cpufreq is loaded. Anything else I'm
missing?
