Oops, that was compiled with the debian make-kpkg tool. Here's the
output from vanilla make modules_install:

make -f arch/i386/lib/Makefile modules_install
if [ -r System.map ]; then /sbin/depmod -ae -F System.map  2.5.42; fi
depmod: *** Unresolved symbols in /lib/modules/2.5.42/kernel/fs/ext2/ext2.o
depmod:         generic_file_aio_read
depmod:         generic_file_aio_write
make: *** [_modinst_post] Error 1

Sorry about that.

Whoops, looks like I missed a couple of exports.  Please apply the patch 
below that adds exports for generic_file_aio_{read,write}.
