I made several tests on two 32-bit systems (both of them have AMD
processors, one uses VIA chipset and another one uses nVidia chipset)
and I cannot reproduce this problem on RELENG_6 (CVSup'ed yesterday).
In yearly 6.1-STABLE this problem with FAST_IPSEC was present.

But, there is one problem on the system with nVidia chipset, and this
problem can have something common with this PR.

If I add "device crypto" to the kernel (even to GENERIC configuration)
and add DRI support to xorg.conf, then starting X server causes system
reboot.  If there is no "device crypto" in the kernel and there is DRI
in xorg.org, then I do not see any problem (ports collection was CVSup'ed
yesterday and all application were reinstalled).

I can give more information if needed.
