Any benefits over the current "sys-kernel/linux-headers-2.6.36.1" ?
There is at least a theoretical benifit if you set NPTL_KERN_VER=2.6.38
in make.conf and recompile glibc. That way glibc could use things not
present in older kernels.
I haven't researched if there are any such things, perhaps someone else
knows.
glibc will use things in newer kernels anyway. You don't need to use
NPTL_KERN_VER=2.6.38 in order for glibc to use 2.6.38 features; it will
do that by default. NPTL_KERN_VER only omits fallbacks for older
kernels. It's there to reduce the size of glibc. The size difference
is very small though.
