Problems with 2.4.5ac21

Hi,

with the newest kernel linux-2.4.5ac21 I am not able to activate the ppp network device an dits options. Regardless what I am doing, the setting will not be stored into .config...

Any trick to avoid this ?

Thanks for any help in advance!

(PS: I am currently not on the kernel list, please answer also to my
email address. Thank you!)

keep hacking the right site of life ! :-)
