: I'm going to remove the option from agp_via.c and agp_sis.c in 6-CURRENT.
: I only wanted the old behavior in RELENG_5.  Can someone that can build
: pc98 releases make sure that things will be OK on the branch?

I know that David know this, but others ask me so often that I thought
I'd share.  Anybody with a i386 box can build at least the kernel for
pc98:

cd src/sys/pc98/conf
config GENERIC			# or make LINK && config LINT
cd ../compile/GENERIC
make

Since the compilers are identical for pc98 and i386, the above works
really well (and is nice since ibm-at compatible machines have
out-paced their NEC PC9801 compatible brethern since NEC stopped
making the latter).

I've built releases in the past with TARGET=pc98 TARGET_ARCH=i386, but
haven't done so recently enough to recommend it.  I have no idea of
that works or not (but suspect it does becaue the .jp pc98 snapshots
are generated this way).
