Actually you've helped with the problem a lot.  I decided to do some 
experiments on when apache will run and when it will not run after a reboot.

Trial One:
1) reboot.
2) apache will not start ( the above alpha_fp_emul error shows up )
3) start X and then close X
4) apache will now start

Trial Two:
1) reboot
2) apache will not start ( the above error again )
3) run " find -name just_start_will_you " from /
4) apache will now start

It seems lots of disk I/O gets apache to start.  One other strange thing was 
MySQL would crash with an unaligned trap when apache would attempt to start 
and fail.  Once I did the " find " from above all those problems seem to stop.

So you can see why I was guessing that it might be the same thing.  I'm 
really needing an automatic solution because this is a server I don't sit in 
front of.  Anything else I could try?  Anything during the boot process I 
could throw in?  Would recompiling apache, etc., help?
