4.9 Stable to 5.2 release upgrade?

[Lucas Holt]

I have a freebsd system with
  4.9-STABLE FreeBSD 4.9-STABLE #4: Fri Jan  2 01:59:31 EST 2004

I'd like to upgrade to 5.2 and would like to attempt to upgrade without 
formatting (cvsup buildworld).  My problem is that I tried to upgrade 
this machine before to 5.0 release and the system wouldn't boot 5.  The 
kernel would consistently panic.  At the time, I assumed it was a 
compatibility problem with my hardware or some piece of flaky hardware 
that didn't show up in windows. freebsd 4.8 or redhat 9.

The hardware:
compaq 4410US:    1.3 gig celeron, 256mb ram (crucial pc133), 40 gb ata 
100 seagate, 3com 10/100 nic (i think its a 905b), onboard intel 
graphics controller.

The last time i tried, i also had an ATI Rage 128 AGP and a Sound 
Blaster Audigy in the system.

I realize I will need to recompile all the ports and software i've 
installed, but i want to know if there is anything about this hardware 
setup that would cause it to flip out on 5.2.

'Re-implementing what I designed in 1979 is not interesting to me 
personally. For kids who are 20 years younger than me, Linux is a great 
way to cut your teeth. It's a cultural phenomenon and a business 
phenomenon. Mac OS X is a rock-solid system that's beautifully 
designed. I much prefer it to Linux.'
