Happens with the kernel headers from the debian package linux-kernel-headers-2.6.999. The file linux/ext2_fs.h exists. This could be a debian bug, too.
If I symlink /usr/include/asm,asm-generic and linux to the 2.6.0-test9/include/* configure complains that it found linux/ext2_fs.h, but it's not useable. See here:

If I try to compile anyway, the following happens:
