Are you saying you run FreeBSD 7 on an 80386(SX/DX) machine?
How exactly did you hack it? As far as I know, support for
80386 processors was removed from FreeBSD a while ago.
For a very short while with 6.0 I was tweaking the kernel to detect 386s
as 486s, as well as using CPU_DISABLE_CMPXCHG and having ok luck. I've
now got a Cyrix 486DrX-2 66 installed in place of my Am386DX-40, which
supports CMPXCHG as well as ID'ing as a 486 so I don't need to do any
tweaking to stay running.
If I can get another viable 386DX box reassembled I'll see if 7 can be
pressed into functioning on it as 6 could.
