So, as we now - only a few posts later - know, that there are no other
rules in the way, we can start looking elsewhere ;)

Hmm, only suggestions available (I have L7 on 2.4.31 and 1.3.2 -
everything is fine). Maybe there is a version mismatch. The kernel patch
is for 2.6.11, whilst you use 2.6.12. Try with kernel 2.6.11 and see if
it works. I will conquer my lazyness and test wether 1.3.3 works with
L7. I'll tell you tomorrow.

Have a nice time,
