The primary reference for config is LINT, not GENERIC. If you read
the information on building a new kernel, it suggests you refer to LINT for
configuration options.
The LINT mentions not once, but twice, that npx is mandatory, as follows:
#####################################################################
# HARDWARE DEVICE CONFIGURATION
...
# Mandatory ISA devices: isa, sc or vt, npx
and
# This device is mandatory.
#
# The Numeric Processing eXtension is used to either enable the
# coprocessor or enable math emulation. If your machine doesn't contain
# a math co-processor, you must *also* add the option "MATH_EMULATE".
# THIS IS NOT AN OPTIONAL ENTRY, DO NOT REMOVE IT
#
device npx0 at isa? port "IO_NPX" irq 13 vector npxintr
I hope that clears it up for you. If you take a few minutes to read
through LINT, the whole config process should be much clearer.
