So, I tried building my own kernel again. But then something happened I definitly don't want to see at all:
CC [M] drivers/net/e1000/e1000_main.o drivers/net/e1000/e1000_main.c: In function `e1000_xmit_frame': drivers/net/e1000/e1000_main.c:2919: internal compiler error: in simplify_subreg, at simplify-rtx.c:2368 Please submit a full bug report, with preprocessed source if appropriate. See <URL:http://gcc.gnu.org/bugs.html> for instructions. For Debian GNU/Linux specific bug reporting instructions, see <URL:file:///usr/share/doc/gcc-3.3/README.Bugs>. make: *** [drivers/net/e1000/e1000_main.o] Error 1 make: *** [drivers/net/e1000] Error 2 make: *** [drivers/net] Error 2 make: *** [drivers] Error 2 make: Leaving directory `/usr/src/linux-source-2.6.17' make: *** [debian/stamp-build-kernel] Error 2
So I not only lost support for my printer up to now, but even waste more time debugging stuff I don't want to see.
