The Maemo SDK runs on top of Scratchbox, which has some problems with Fedora kernels and memory managers. If you see an error like this when trying to log in in your scratchbox environment:

Inconsistency detected by rtld.c: 1192: dl_main: Assertion `(void *) ph->p_vaddr == _rtld_local._dl_sysinfo_dso' failed!

Then you can try this:

# su -
# echo 0 > /proc/sys/vm/vdso_enabled

Note that the script will fail if you don't disable the vdso kernel feature as above.
