Network Card problems in FreeBSD 4.9

[Steph]

Hi There,
 
I've recompiled my kernel since I needed to add a new Driver for some
bandwidth management software I'm running and for some reason when I
reboot the box with the new kernel it doesn't show my Network Interfaces
when doing an ifconfig -a. 
 
The one device is a Dual Intel Pro/1000 Adaptor and the other is a Dual
Broadcom I think. I've compiled the drivers for these devices directly
into the kernel without any errors. They do show up when doing a pciconf
-lv. I'm new to FreeBSD so the chances that I've screwed something up
somewhere is quite good :-) Is there anything else I should be looking
out for?
