EAP-FAST Internal Crypto Libraries take a lot of time

I am trying to test wpa_supplicant-0.5.7 on a custom ARM board and using
EAP-FAST as the authentication.
Radius Server is Steel Belted Radius(eval version) and the authenticator
is Cisco Aironet 1100 Series.
I am using the internal TLS and crypto libraries and have
CONFIG_INTERNAL_LIBTOMMATH enabled for bringing down the size.
We have only 128K of Flash on the board and 192K RAM for execution.
I find that during EAP-FAST authentication, after the server has sent
out a Server Hello Message, the code keeps looping infinitely in the
function s_mp_exptmod in a for(;;) loop. It takes atleast 10 mins before
the function returns :-(
Is this behaviour because, the run time memory is not enough or the
processor is pretty slow.
Any pointers or help please ?
