Friendly Name on Broadcom NC373i

I have a customer which is using an application on W2K8 R2 that relies on  the "friendly name" of the Broadcom NIC,

so the application  wants NC373i DP Multifunction Gigabit Server Adapter #1  and  #2.

On his server (DL380G5 with 2 NIC's integrated on it), both NIC's has the friendly name #48 and #49 instead of #1 and #2.

How can I change that back to the low values ?? 

I've tried that by uninstalling the NIC's in cp/system; (but #48 and #49 stays)

i've looked for hiddendevices via 'set devmgr_show_nonpresent_devices=1' and then Show hidden devices

(but there are no hidden NIC's)

i've tried within the registry (but after modify it (replace ownership); it was not saved)

So, is there anybody knows how to do that ???
