I tried to do make config on the linux-2.4.9-pa17 kernel tree using the pa17 kernel, which resulted in:

This is on a C240.

Unlike Jurriaan's Trace/Breakpoint trap. Mine does not crash the OS or write to syslog.

I don't, but I can tell you I have the same problems on my C200 with the same kernel - check out the whole 'Trace/breakpoint' thread.
