I've just returned from EuroBSDCon and is still wading through tons of
mail, so I beg pardon in advance for a rash reply.

1) What does booting with serial console shows?

1.5) hpcboot compiled with debugging enabled might be helpful to glean
some hardware details, but we are back to swuare one with the lack of
the toolchain :(
 
2) trim GENERIC to make a machine specific kernel?

3) DEBUG kernel?

4) custom binary-search printf debugging?


I think it shouldn't be hard to support 360LX if hpcboot works on it.
It takes just someone with an actual machine and a little bit of
determination.

Feel free to ping me privately.  I'll be busy with job stuff for the
next couple of weeks, so don't get discouraged if I don't reply
immediately.

SY, Uwe
