A couple people asked me, "Hey, could you put all that stuff up for ftp?".
So anyway, I did.  Binaries and source code diffs both.  You can get it at:

ftp://ftp.netbsd.org/pub/NetBSD/arch/i386/1.5-XF86-4.0.2-fixes

I'd be interested in hearing whether or not this works for people, so
if you try it, please let us know either way!  Also, if you have the
same problem with XFree86 4.0.2 (very dim screen on server exit) and
it's _not_ a Neomagic chipset, drop me a line; I'll see if the same problem
exists in that driver.
