Hi,
I just tried to boot a current kernel on my trusty, old
486DX-based machine. It panicked very early in the boot sequence
with a "supervisor trap privileged instruction fault". To me it
seems that the kernel tried to use a not implemented instruction
on this CPU.
Ten finger dmesg and backtrace:
NetBSD 4.99.49 .....

Don't tell me that we have also de-supported the 486-class of
CPUs.
