Does anyone know why the option "8xx" in the "Processor Type" screen of the menuconfig is gone ?

It's not gone, it just depends on CONFIG_BROKEN. A lot of code was finally synced up, but since it's not fully functional (it's the same state as was in linuxppc-2.5), it requires CONFIG_BROKEN to be set.

Is anyone working on a fix already ?
Will the MPC8xx support be functionnal for 2.6.10 ?

Thanks.

Not actively. The problem has been described on the list a few times (it seems like there's a stale TLB entry).

In my spare time, which I have little of right now. I know the symptom, as Tom mentioned, but not the cause.
