Oh, for oldstyle it is needed. You're right. It is better to keep it in
the defconfig. Just drop the hunk from the patch that I sent you.

Oh... :-(
I will post the problems that I get with MTD on my kurobox so that
people from both the linux-mtd/linuxppc-dev lists can see what is
happening and suggest some fixes.
Thanks, Rogério Brito.

Thanks. The MTD & PHYMAP_COMPAT are the things that have been bugging me
and my main reason to keep with the bleeding edge kernels is to get things
whey they were (regarding mtd) as in kernel 2.6.28.
As I have no experience with MTD devices, I would appreciate a reference to
their workings... All that I know is that all my /dev/mtd* devices are gone
if I boot a 2.6.29* kernel.
Of course, I can do a git bisect process (since the MTD subsystem doesn't
work as it did in the past even if I enable PHYMAP_COMPAT and put the same
settings there, quite unfortunately).

No problems with that. I will do that ASAP. Thanks for your kind comments.
Regards, Rogério Brito.
P.S.: Guennadi, did you see any regressions with your linkstation/kurobox
HG or whatever device you have?
