No EAP-TLS with XP SP3 ?

I have a lot of problems doing an EAP-TLS authentification with 
Freeradius 2.1.3. We're doing a machine-based authentification with 
certs, using EAP-TLS with 802.1x capable Linksys switches (cable based).

We had NO problems at all with Freeradius 1.1.0 and Windows 2000 SP4 and 
XP SP2 and Linux. We're using no Vista machines at all.

With XP SP3 the auth failed, I googled that FR 1.1.0 is not capable to 
do this, because SP3 is realizing the same 802.1x engine as Vista does. 
So I upgraded to 2.1.3 and compiled it on OpenSuse 10.1 without errors 
and the software runs without problems. But the auth still doesn't work. 
I'am a bit confused about the new inner-tunnel and a few options I'am 
not aware of from my FR 1.1. setup. Is there somewhere a walk-thru 
published to make XP SP3 work with FR again?
