>Description:
	According to MOCHIDA Shuji in messages sent to port-i386 by Sep 26
	2001, Netscape Solaris x86 crashes kernel after a while, like:
 % netscape -display xxx:0
 unknown svr4 fast trap 2
 unknown svr4 fast trap 2
 uknknown svr4 faste trap 2
 rnel: type 1216652891 trap, code=0

>How-To-Repeat:
	Possibly by running the netscape binary in archive
	navigator-v475-us.x86-sun-solaris2.5.1.tar.gz. 
>Fix:
	May be related to %fs/%gs changes - according to  MOCHIDA Shuji:
"""
 I compiled many kernels, and found that 'cvs update -D 2001-06-18' one
works good, 'cvs update -D "2001-06-18 10:00"' one does not. I can't tell
the cause exactly, but it seems that is related to the change:

    http://mail-index.netbsd.org/source-changes/2001/06/18/0000.html
"""

	I will track this further, this PR is reminder to not forget
	to fix this (or confirm it's no longer problem).
