This message shows, that you have in kernel ppp 2.3.3 part, not 2.3.5

Probably "make kernel" don't copied ppp.c from pppd 2.3.5 sources to 
kernel sources three, because it has earlyer fileversion than kernel 
sources one, and you compiled and installed older module.

Take look to 

http://www.tartu.customs.ee/linux.shtml

there are described some pppd compile problems and solutions.

I repeat, you have first to match ppp versions in pppd daemon and 
kernel part. Also I suggest you to compile ppp directly to kernel, 
not as module and you will have less problems.
