This may be a xf86 problem, so let me know.  I've been running
netbsd-current on my roommates machine for the past 2 weeks, along with
xfree86-2.0, just fine.  About two days ago the machine started
rebooting upon starting up the x server.  I've done a bit of playing and
have found that it isn't the probe code (because XF86_SVGA -probeonly
doesn't reboot, whereas XF86_SVGA by itself does).  The output from
XF86_SVGA looks fine to me (i'll paste it at the end of this message).

We didn't change any major parts of the system when it started doing
this, so I don't think that there are any problems there.  I also know
that my copy of XF86 is fine, because the same copy (we have it mounted
off of nfs) works fine on my computer.

We were running NetBSD-current as of about 3 weeks ago until today, but
we didn't recompile any of the binary trees (we were mostly interested
in playing around with shared X).  I did use the shared X stuff that
someone else posted about, but this breaks regardless of our use of that
or not.  Today I recompiled the NetBSD-current as of yesterday on
sun-lamp (in tar_files), including all of the system binaries (usr.bin,
usr.sbin, sbin, and bin).  Still no luck.

Here is his machine configuration: IBM 486SLC2/66 (this is an odd IBM
chip that is a 486sx with a 16-bit external data path an a 16k internal
cache), ITT 387sx/33 (could this be a problem?  i've heard bad things
about these chips), 8.5 megs of memory (two 4 meg simms, two 256k
simms), two ide hard drives (340+100), Orchid Prodesigner IIS video
card, and a Sony 14" triniton monitor.  The resolution that we set the
xconfig up for doesn't seem to matter.

The kernel is pretty much stock, with the addition of the syscons
driver.  here is the config file:

Like I've said, I'm not sure if this is a netbsd problem or a XF86
problem, so let me know.

Here is the output from running the server (from another terminal):
