This problem comes up occasionally on other BSD lists, and not only with 
3com cards. It seems to not have been completely tracked down (but I 
don't follow it too closely), but the four suggestions seem to always be:

1. drivers - solution: change nic
2. BIOS - solution: update the BIOS (helped someone on the m0n0wall 
list, iirc)
3. bad nics - solution: change nics
4. IRQ conflicts - check the BIOS, turn off unused devices (USB ports, 
etc) that use IRQs and hope that upon reboot, each nic gets its own IRQ 
or manually assign them

since you said you changed the nics around in the PCI slots, #4 might 
have well been your problem ind been resolved through this change.
