BTW... I'd really like to have a database of machine, kernel version,
cpuinfo, config... So that questions like "what is the latest kernel
that is known to be running on this hardware" and "what config should
I start from".

For example, I have nokia N810 here. It was supported by Linux at some
point, but then we moved to dts, and stuff changed, and I can no
longer figure how to boot it.

I guess "what was last kernel that worked on Cyrix MII" is also
relevant question.

Is there such database? If not, would people be interested in
contributing if I create one?
