I have a kernel (2.4.22 Benh) that works fine except for
decrypting.
Are you using the kernel sources from Debian, or Ben's tree itself?
well i suppose its debian sources, but havent downloaded it myself.
just mirrored the whole system from a friend with same hardware. as i
understood cryptopatch doesnt work with that version.
Well, the crypto patch doesn't work with 2.4.22 because it is already
*in* this Kernel ;-).
Have a look in the .config file, at the end you will see several lines
CONFIG_CRYPTO[...]. If they aren't there reconfigure your kernel with
cryptographic support.
