I tested this patch with 2.6.37-rc6. Not sure whether 
I'm doing something wrong, but I failed to start the
PPP daemon with my speedtouch usb:

Dec 17 14:17:24 absol pppd[4853]: Plugin pppoatm.so loaded.
Dec 17 14:17:24 absol pppd[4853]: PPPoATM plugin_init
Dec 17 14:17:24 absol pppd[4853]: PPPoATM setdevname_pppoatm - SUCCESS:8.48
Dec 17 14:17:24 absol pppd[4854]: pppd 2.4.4 started by root, uid 0
Dec 17 14:17:24 absol pppd[4854]: connect(8.48): No such device
Dec 17 14:17:24 absol pppd[4854]: Exit.

Dec 17 14:17:26 absol rc-scripts: Failed to start the PPP daemon


Without the patch:

Dec 17 14:19:19 absol pppd[4847]: Plugin pppoatm.so loaded.
Dec 17 14:19:19 absol pppd[4847]: PPPoATM plugin_init

Dec 17 14:19:19 absol pppd[4848]: pppd 2.4.4 started by root, uid 0
Dec 17 14:19:19 absol pppd[4848]: using channel 1
Dec 17 14:19:19 absol pppd[4848]: Using interface ppp0
Dec 17 14:19:19 absol pppd[4848]: Connect: ppp0 <--> 8.48
