4.8 on Proliant 8500

[Secure Play]

Has anyone seen any issues runing FreeBSD 4.8 on a Compaq Proliant 8500? This is an older 8-way server (2GB ram, 8x500 Mhz CPUs). I don't really need all those CPUs, but I have nothing else to do with them. :)
 
Everything works fine, except that when I add a Intel Pro/1000 card, it is not seen.  I also tried an equivalent compaq gigabit card with the same results (I believe they share the same chipset). I don't know what else to do to it, the bios sees them, I have the latest updates from Compaq/HP, and I eventually recompiled the kernel with the latest drivers from the intel website. Everything else seems to work fine, although admittedly this is the only "up" card that I have in this box.  I also tried various slots (the box has three busses) and no luck.
 
 
The same card is seen on a newer DL380/G2.
 
On the 8500, pciconf does not see this card at all.. The card is correctly installed, has link light, etc.
